Vulnerabilities

Cisco AsyncOS Software for Cisco Secure Email Gateway contains a SQL injection flaw (CWE-89) in its email parsing logic, caused by insufficient validation of message content. An unauthenticated, remote attacker can trigger it simply by sending a crafted email containing malicious SQL statements through an affected gateway, with no user interaction required. Successful exploitation allows arbitrary SQL execution that escalates to arbitrary operating-system command execution with root privileges, fully compromising the appliance and all mail flowing through it. Any organization running an affected version of Cisco Secure Email Gateway is impacted, and because these appliances sit on the inbound mail path they are inherently reachable over the network. There is no known public proof-of-concept, the flaw is not on the CISA KEV list, and no in-the-wild exploitation has been reported to date, though the CVSS 9.8 rating makes patching urgent.

Do: Upgrade to the fixed AsyncOS release listed in the corresponding Cisco PSIRT advisory as soon as possible, since the flaw is unauthenticated, requires no user interaction, and yields root. Until patched, apply any Cisco-documented workarounds and tightly restrict which hosts can submit mail to the gateway where operationally feasible. Review mail and system logs on these appliances for anomalies such as SQL errors in parsing, unexpected processes, or unexplained outbound connections that could indicate exploitation attempts.

CVE-2026-85706 is a path traversal flaw (CWE-35) in GitLab Community Edition and Enterprise Edition in which the repository commits API does not properly confine file paths and does not enforce authentication, allowing an unauthenticated attacker to read arbitrary files from the GitLab server. It is triggered by sending a crafted unauthenticated request to the commits API that supplies traversal sequences moving outside the intended repository path. An attacker gains the ability to read arbitrary files on the host, which can expose configuration files, certificates, and stored credentials or keys; related reporting on the recent GitLab patch wave also notes credential theft and code execution flaws, though this CVE itself is the file-read issue. All self-managed GitLab CE and EE deployments are in scope, and CISA did not publish specific affected version ranges in this data. The flaw was added to CISA's KEV catalog on 2026-09-11 and is being actively probed and exploited in the wild within a day of disclosure, with three public proof-of-concept repositories available; ransomware use is not yet confirmed.

Do: Upgrade GitLab CE/EE to the patched release identified in GitLab's security advisory (no specific fixed version number is provided in this data), prioritizing internet-facing instances in line with CISA BOD 26-04; if patching is not immediately possible, restrict exposure and review access logs for unauthenticated requests to the commits API containing path traversal sequences. Because arbitrary file read can expose server-side secrets, inventory and rotate credentials, tokens, and keys stored on or reachable by affected GitLab hosts.

CVE-2026-84869 is a critical authorization flaw (CWE-862 missing authorization, CWE-269 improper privilege management) in the ScreenConnect client, the endpoint-side agent of ConnectWise's widely used remote access and remote support platform, in which files can be transferred to a machine and executed during an active remote session without the expected authorization or without confirmation by the Host (technician). It is triggered in certain circumstances during an active session, with a network attack vector, low attack complexity, low privileges required, and no user interaction per the CVSS 3.1 vector. An actor who obtains or already holds access to a session context could thereby push and run files on the managed endpoint, potentially achieving code execution with high confidentiality, integrity, and availability impact (CVSS 3.1 score 9.9, scope changed). Only endpoints running the ScreenConnect client are affected; ScreenConnect servers are not impacted, and the affected client version ranges are governed by ConnectWise security advisory AV26-903 (not enumerated in the available data). The flaw is not currently known to be exploited: it is not in CISA KEV, no public proof of concept is known, and EPSS assigns a modest 0.4% probability of exploitation within the next 30 days (32nd percentile).

Do: Follow ConnectWise security advisory AV26-903 and update ScreenConnect clients to the patched version it specifies, noting that ScreenConnect servers do not require remediation. Until patching is complete, monitor active remote sessions, require Host confirmation for file transfers, and review recent sessions on high-value endpoints for unexpected transferred or executed files; given no known exploitation and the active-session prerequisite, prioritize endpoints routinely accessed remotely.

Adobe Commerce and Magento (including Adobe Commerce B2B) contain an improper neutralization of special elements used in a template engine (CWE-1336), a template-injection flaw that permits arbitrary code execution in the context of the current user. The flaw is reachable over the network by unauthenticated attackers, requires no user interaction, and its changed scope (CVSS 3.1 S:C) means injected code executes beyond the vulnerable component, producing a maximum-severity (CVSS 10.0) remote code execution condition. A successful attacker gains arbitrary code execution on the storefront server; in the observed campaign, intruders installed a Rust backdoor and a PHP web shell (dubbed 'StyleSmuggler') on compromised servers. Any organization running an Adobe Commerce, Adobe Commerce B2B, or Magento storefront is in scope, with internet-facing e-commerce deployments most exposed. Exploitation is confirmed in the wild: the bug was abused as a zero-day before patching and was added to CISA's Known Exploited Vulnerabilities catalog on 2026-09-08.

Do: Apply Adobe's released patches immediately per vendor instructions, prioritizing internet-facing Commerce/Magento storefronts, and ensure compliance with CISA BOD 26-04 timelines for KEV entries. Hunt for 'StyleSmuggler' indicators of compromise, including unexpected Rust backdoor binaries and PHP web shells on hosts, and review template/theme customizations for tampering. Exact fixed version numbers are not included in the available data, so consult Adobe's advisory for the correct patched release for your Commerce/Magento version line.

CVE-2026-86218 is a static code injection flaw (CWE-96) in N-able's N-central on-premises remote monitoring and management (RMM) platform, carrying a maximum CVSS 4.0 score of 10.0. An unauthenticated, remote attacker triggers it by sending crafted network input to the N-central server that is improperly neutralized and persisted into application-managed code, which the server then executes — no privileges (PR:N) or user interaction (UI:N) are required. Successful exploitation yields full server compromise with high impact on confidentiality, integrity, and availability, and because N-central acts as the management hub for downstream customer endpoints, compromise can expose the entire managed estate. Any organization running an affected N-central release (before 2026.3.1.14) — primarily MSPs and corporate IT departments using N-able RMM — is affected. The flaw is confirmed exploited in the wild: N-able patched it as a zero-day, CISA added it to the KEV catalog on 2026-09-08, and it is the fourth N-central hotfix in five weeks, though no public PoC is known and ransomware use is unknown.

Do: Upgrade N-central to 2026.3.1.14 or later (or apply N-able's hotfix) immediately, as the flaw is in CISA's KEV catalog and BOD 26-04 timelines apply to federal stakeholders. Until patched, remove direct internet exposure of the N-central server (restrict to VPN/management networks via firewall allowlists) since no authentication is needed for exploitation. Because in-the-wild exploitation is confirmed, review internet-facing N-central servers for indicators of compromise such as unexpected processes, unusual child processes of the web service, and new or suspicious accounts.

CVE-2026-86060 is an argument-injection flaw (CWE-88) in MikroTik RouterOS's SSH login path: when a login supplies a username beginning with a prohibited character, the RouterOS login helper mishandles the argument, allowing the trusted RouterOS policy mask to be changed and privileges to be escalated. An unauthenticated attacker only needs the ability to reach the router's SSH service, since exploitation happens during the SSH login process itself. By altering the policy mask the attacker gains elevated rights on the device, and news reports indicate attackers have used this technique — including logins with usernames such as '-2' — as part of chains that take over routers without needing a password. Any RouterOS deployment running versions before the fixes (6.49.21 Long-term, 7.23.4 Long-term, 7.24.2 Stable) with SSH enabled or reachable is affected, with internet-exposed SSH at highest risk. Multiple outlets report the RouterOS flaws are being actively exploited in the wild, although no public proof-of-concept is known and the flaw is not yet in CISA KEV.

Do: Upgrade RouterOS to 6.49.21 (Long-term), 7.23.4 (Long-term) or 7.24.2 (Stable) as applicable. Until patched, restrict SSH (TCP 22) to trusted management networks or disable the SSH service if unused, and review authentication logs and user/group policy settings for tampering — reports indicate attackers log in with usernames beginning with '-' (e.g., '-2').

CVE-2026-83548 is a critical (CVSS 3.1 score 10.0) server-side request forgery (SSRF) vulnerability in the Workplace interface of SonicWall SMA1000 appliances, caused by an unintended alternate access path (unprotected alternate channel, CWE-441; SSRF, CWE-918). Because it is pre-authentication, any remote unauthenticated attacker who can reach the interface can trigger it and gain unauthorized access to sensitive functionality and perform unauthorized operations. CISA lists all SonicWall SMA1000 appliances as affected, with CPE data naming the SMA 8200v and SMA 6210/7210 firmware; internet-exposed units are at highest risk. The flaw is being actively exploited in the wild: it was added to CISA's Known Exploited Vulnerabilities catalog on 2026-09-02 alongside companion zero-day CVE-2026-83549, which reporting suggests may form an attack chain with this SSRF. Exploitation probability is elevated (EPSS 4.7%, 91st percentile) and no public proof-of-concept is known.

Do: Apply the fixes/mitigations from SonicWall security advisory AV26-872 (Update 1) immediately, prioritizing internet-exposed SMA 1000 appliances, and treat companion zero-day CVE-2026-83549 as requiring remediation in the same maintenance window. Review SMA 1000 logs for signs of exploitation (unexpected access to or requests against the Workplace interface) and reduce internet exposure of that interface where feasible. Per the CISA KEV required action and BOD 26-04, patch per vendor instructions or, where mitigations are unavailable, evaluate each asset's internet exposure and discontinue use of the product until remediated.

JFrog Artifactory contains an improper authentication flaw (CWE-287) that, under the product's default configuration, can let an unauthenticated attacker with network access obtain administrative privileges. The weakness is reachable over the network with no privileges or user interaction required, which is why it carries a critical 9.8 CVSS 3.1 score; an attacker who succeeds effectively gains full administrator control of the artifact repository, and public reporting describes attackers using the flaw to mint admin tokens days after disclosure. Any organization running JFrog Artifactory is in scope — CISA's entry lists the product without version detail, so deployments should verify their versions against JFrog's advisory (AV26-867, Update 1) — with internet-exposed instances at greatest risk. Exploitation is confirmed in the wild: CISA added the CVE to its Known Exploited Vulnerabilities Catalog on 2026-09-02, a public proof-of-concept is available, and news headlines report active exploitation alongside related Artifactory flaws CVE-2026-42016 and CVE-2026-42018.

Do: Upgrade Artifactory to a fixed release per JFrog's advisory AV26-867 (Update 1) — the exact affected and fixed versions are not specified in this data, so check the advisory before patching. Until patched, restrict network access to the Artifactory UI and APIs to trusted sources (VPN/firewall allowlists) and review the instance for unauthorized admin tokens or accounts, as in-the-wield attackers have been minting admin tokens. CISA KEV stakeholders must apply mitigations in line with BOD 26-04 within the required timeline or discontinue use of the product.

CVE-2026-82078 is an unsafe dynamic class loading flaw (unsafe reflection, CWE-470) in the database connection utilities of PaperCut NG and PaperCut MF: the software instantiates a database driver class based on a configurable driver name without validating it against an allowlist of approved drivers. An attacker who can manipulate system configuration parameters can point that setting at classes of their choosing, causing the server to execute arbitrary Java bytecode residing on the application classpath in the security context of the PaperCut server process. On its own the issue is rated 9.4 (Critical) with high privileges required, but when chained with the companion authentication bypass CVE-2026-81578 it yields unauthenticated remote code execution on the print-management server. All PaperCut NG and MF deployments are in scope; affected version ranges were not specified in the available data, so administrators should consult PaperCut's advisory for fixed versions. The flaw is confirmed exploited in the wild as a zero-day: it was added to CISA's KEV catalog on 2026-08-31, and public reporting describes an AI-orchestrated campaign that compromised PaperCut servers at roughly 395 organizations (~440 servers), with EPSS currently at 1.7% (76th percentile).

Do: Upgrade PaperCut NG and MF to the patched release specified in PaperCut's security advisory (exact fixed versions were not provided in this data), prioritizing internet-exposed print servers; the KEV listing means agencies must remediate per CISA BOD 26-04 or discontinue/mitigate per its cloud-service guidance. Restrict the PaperCut web interface from direct internet exposure (VPN/allowlist), review administrator accounts and database driver configuration for tampering, and hunt for post-exploitation activity, since this flaw is being actively chained with the authentication bypass CVE-2026-81578.

Gitea before 1.27.1 contains a critical code injection flaw (CWE-94) in the diffpatch API that allows remote code execution by causing the installation of a Git hook. An attacker can submit a crafted request through the diffpatch API to plant a Git hook, which then executes arbitrary shell commands on the server when Git operations run; the CVSS vector indicates the attack requires no authentication or user interaction, while public reporting describes attackers with repository write access planting hooks to run shell commands. Successful exploitation yields full server compromise (confidentiality, integrity, and availability all rated high), and observed attacks have reportedly dropped a cryptocurrency miner. All Gitea deployments running versions prior to 1.27.1 are affected, with internet-facing instances at greatest risk; public scans identified over 8,300 vulnerable Gitea servers. The flaw is actively exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-25, and EPSS estimates an 86.8% probability of exploitation within 30 days.

Do: Upgrade Gitea to version 1.27.1 or later immediately; organizations subject to BOD 26-04 must apply the vendor mitigation or discontinue use of unpatched cloud-hosted instances. Until patched, limit internet exposure of Gitea servers and inspect repository hook directories for unauthorized or recently modified hooks that could serve as persistence. Check for signs of compromise, including unexpected processes or cryptocurrency-miner activity, since in-the-wold attacks reportedly deploy a miner.

TrueConf Server contains a code injection flaw (CWE-94) that allows a remote, unauthenticated attacker with network access to TCP port 4307 to send a specially crafted script that breaks out of the server's isolated environment and executes arbitrary code on the underlying host. The flaw affects TrueConf Server 5.3.X through 5.3.9, 5.4.X through 5.4.9, 5.5.X through 5.5.5, and earlier releases. A successful attack yields full code execution on the host system, not just the conferencing application, although the critical CVSS 4.0 score of 9.5 includes high attack complexity and attack-requirements factors. Organizations running self-hosted TrueConf video conferencing servers, especially those with port 4307 exposed to untrusted networks, are in scope. Exploitation is confirmed in the wild: CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-08-20, a public PoC exists, and Kaspersky's Securelist reports the Head Mare threat actor has actively targeted TrueConf Server to deploy PhantomCore malware.

Do: Upgrade TrueConf Server to a fixed release beyond the affected ranges (later than 5.5.5, per vendor instructions) as the primary remediation. Until patched, restrict access to TCP port 4307 so it is not reachable from untrusted networks and review server logs for signs of exploitation. U.S. federal agencies must apply these mitigations in accordance with BOD 26-04 following the KEV listing (added 2026-08-20), or discontinue use of the product if mitigations are unavailable.

Citrix NetScaler ADC and NetScaler Gateway contain an authentication-bypass vulnerability (CWE-288, 'using an alternate path or channel') that an unauthenticated remote threat actor can exploit. The flaw is triggerable when the appliance is configured as an AAA virtual server or as a Gateway, including SSL VPN, ICA Proxy, CVPN, or RDP Proxy deployments, allowing the attacker to bypass authentication without valid credentials. A successful bypass could give an attacker access to VPN-protected or AAA-gated resources as an authenticated user; no CVSS score has been published yet. Organizations running affected NetScaler appliances in these configurations are exposed, and affected version ranges are not specified in the available data, so defenders should consult Citrix advisory AL26-019. The flaw was added to CISA's KEV on 2026-09-09, indicating exploitation in the wild; ransomware use is unknown, no public PoC is known, and EPSS assigns a 3.4% probability of exploitation within 30 days (88th percentile).

Do: Prioritize applying vendor fixes or mitigations per Citrix advisory AL26-019 in line with CISA BOD 26-04, focusing first on internet-facing appliances configured as AAA virtual servers or Gateways (SSL VPN, ICA Proxy, CVPN, RDP Proxy). Until patched, restrict internet exposure and review VPN/AAA authentication logs for signs of unauthenticated access, following CISA's Forensics Triage Requirements if compromise is suspected.

MLflow versions prior to 3.15.0 contain a server-side request forgery flaw (CWE-918) in the unauthenticated POST /api/2.0/mlflow/webhooks/{id}/test endpoint. The webhook URL is validated only for the original request, but delivery follows redirects and re-resolves the hostname without pinning the validated address, letting an attacker redirect server-side requests to internal network services or cloud instance metadata endpoints. Because the endpoint returns response_status and response_body, attackers can read internal service responses and, per public reporting, steal cloud credentials and secrets from metadata services. Any self-hosted MLflow deployment is affected, with internet-exposed servers at the highest risk. Exploitation is confirmed in the wild: CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2026-08-19, and headlines report active attacks stealing cloud credentials; EPSS puts 30-day exploitation probability at 16.4% (97th percentile).

Do: Upgrade to MLflow 3.15.0 or later immediately, prioritizing any MLflow server reachable from the internet. Until patched, restrict network access to MLflow (especially the /api/2.0/mlflow/webhooks/{id}/test endpoint), place it behind authentication or a reverse proxy, and review webhook logs for unexpected test requests and cloud metadata endpoint access; rotate cloud credentials and secrets if compromise indicators are found. Federal agencies must apply vendor mitigations in accordance with CISA BOD 26-04 guidance or discontinue use if mitigations are unavailable.

CVE-2026-72898 is a critical SQL injection flaw (CWE-89, CVSS 4.0 score of 10) in Metabase, a widely used open-source business intelligence platform. A remote, unauthenticated attacker can send crafted input to the '/reset_password' database endpoint to inject arbitrary SQL into the underlying database. Successful exploitation grants the attacker administrator access to the connected Metabase instance, with confidentiality, integrity, and availability impacts rated high in the CVSS 4.0 vector. Any organization running an affected Metabase instance, particularly one exposed to the internet, is at risk. The flaw is a zero-day being exploited in the wild, was added to CISA's Known Exploited Vulnerabilities catalog on 2026-08-11, and carries a 94.2% EPSS probability of exploitation within 30 days (100th percentile).

Do: Upgrade promptly to the fixed Metabase release identified in the vendor's security advisory (no version numbers were provided in the available data), as the flaw is being exploited in the wild and is on CISA's KEV list under BOD 26-04. Until patched, restrict internet access to Metabase and limit reachability of the '/reset_password' endpoint to trusted networks. Hunt for compromise by reviewing access logs for anomalous requests to the reset-password endpoint and checking for unexpected administrator accounts or changed admin credentials.

CVE-2026-65400 is a critical (CVSS 9.8) improper authentication flaw (CWE-287) in Apple macOS's Screen Sharing service, caused by an authentication state-management defect. An attacker who can reach a vulnerable Mac's Screen Sharing service over the network can authenticate without valid credentials, gaining full remote access with high impact to confidentiality, integrity, and availability. All three currently supported macOS branches are affected: Sequoia, Sonoma, and Tahoe, in versions prior to the fixed releases. The flaw is being actively exploited on the internet, with public reporting that attackers use the bypass to deploy Monero cryptominers, and CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-18. EPSS estimates a 9.9% probability of exploitation within 30 days (95th percentile).

Do: Upgrade to macOS Sequoia 15.7.9, macOS Sonoma 14.8.9, or macOS Tahoe 26.6.1 (or later) immediately; patching is mandatory for federal agencies under CISA BOD 26-04 given the KEV listing. As an interim mitigation, disable Screen Sharing or restrict it via firewall/VPN so VNC (port 5900) is not reachable from the internet. Review internet-exposed Macs for signs of compromise, especially unexplained Monero miner processes or abnormal CPU usage.

CVE-2026-59310 is a directory traversal (CWE-22) vulnerability in the Syslog server component of VMware vCenter Server, rated critical at CVSS 9.8. It can be triggered over the network without authentication or user interaction, allowing a malicious actor with network access to vCenter to achieve arbitrary code execution. An attacker who exploits it gains code execution on the vCenter appliance, and reported campaigns show it has been used to establish persistent remote access and, by a suspected China-nexus actor, to deploy Babuk ransomware. Any organization running an affected version of vCenter Server is exposed, especially where the management interface is reachable from the internet; the available data does not specify affected version ranges. Exploitation is confirmed in the wild: CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2026-08-18, it was reportedly exploited just five days after disclosure, and EPSS estimates a 45.9% probability of exploitation within 30 days (99th percentile).

Do: Upgrade vCenter Server to the patched release identified in Broadcom's advisory (no specific version ranges are provided in this data) and prioritize any vCenter that is internet-facing, in line with CISA KEV and BOD 26-04 requirements for federal agencies. Until patched, restrict access to the vCenter management interface to trusted networks and verify whether the vCenter Syslog server is enabled. Hunt for compromise indicators, including unexplained remote-access persistence and Babuk ransomware artifacts, given the documented China-nexus exploitation.

CVE-2026-63077 is a critical (CVSS 9.8) unauthenticated remote code execution vulnerability in JetBrains TeamCity, caused by deserialization of untrusted data (CWE-502) in the agent polling protocol. An attacker with network access to the TeamCity server, but no credentials of any kind, can send maliciously crafted serialized input to the agent polling endpoint and execute arbitrary code on the server. Successful exploitation yields full server takeover, exposing source code, build logs, stored secrets and credentials, and providing a pivot point into build agents and connected infrastructure; related headlines describe a real breach in which AWS credentials were extracted from an unpatched TeamCity instance. Organizations running TeamCity On-Premises in versions prior to the fixes (2025.11.7 or 2026.1.3, depending on branch) are affected, while the JetBrains-hosted cloud service is not indicated as impacted. Exploitation is confirmed in the wild: CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-08-05, EPSS is 86.5% (100th percentile), and no public PoC is known, meaning defenders cannot rely on public scanners alone and should assume sophisticated attackers are targeting exposed servers.

Do: Upgrade immediately to TeamCity 2025.11.7 or 2026.1.3, whichever branch you run; because the flaw is pre-authentication, also hunt for signs of compromise (unexpected builds or agents, new or modified admin users, altered build configurations, and leaked stored credentials/secrets) per vendor guidance, and restrict internet exposure of the TeamCity server until patched. Federal agencies must apply vendor mitigations or discontinue use per CISA BOD 26-04 and the KEV required action, including the Forensics Triage Requirements.

Arista VeloCloud Orchestrator (VCO) On-Prem, the centralized management platform for VeloCloud SD-WAN networks, contains an OS command injection vulnerability (CWE-78) that allows a remote attacker to execute operating system commands, reach privileged internal functionality, and impact the underlying VCO host. The available advisory text does not describe the exact injection point or authentication requirements, but the flaw is exploitable remotely against the on-premises orchestrator. A successful attack can compromise the confidentiality, integrity, and availability of the orchestrator and of the configuration and network data it manages. Organizations running an on-premises VeloCloud Orchestrator are affected; CISA scopes the flaw to the on-prem product, provides no version ranges in this data, and no CVSS score has been published yet. The flaw was added to CISA's KEV on 2026-07-27, confirming exploitation in the wild, while ransomware use is unknown, no public proof-of-concept is available, and EPSS currently puts 30-day exploitation probability at 1.6% (74th percentile).

Do: Follow Arista's VeloCloud security advisory: match your on-prem VCO release against the advisory's affected list and apply the fixed update as soon as possible, as required for U.S. federal agencies under BOD 26-04 by the CISA deadline. Until patched, restrict the orchestrator's web/API access to trusted management networks or VPN, verify whether your VCO is internet-exposed, and hunt for signs of unexpected command execution or privileged activity on the VCO host per CISA's forensics triage requirements; if mitigations are unavailable, follow BOD 26-04 guidance on discontinuing use of the product.

Check Point SmartConsole, the administrative client used to manage Quantum Security Management and Multi-Domain Security Management, contains an authentication bypass (CWE-287) in its login process that allows an unauthenticated remote attacker to obtain an application login token and authenticate with full administrative privileges. Exploitation is possible when the Management Server IP address is reachable from the internet and the configuration does not restrict Trusted Clients. A successful attacker can modify security policies and security configurations, effectively taking control of firewall management. Any organization running an internet-exposed Check Point management server without Trusted Client restrictions is affected, though Check Point reports exploitation has impacted only a very small number of customers. The flaw was added to CISA's KEV on 2026-07-22, is actively exploited, and press reports indicate public proof-of-concept code has been released.

Do: Apply the fix released in Check Point's advisory for CVE-2026-16232 by updating SmartConsole and the associated Quantum/MDS management software; no fixed version numbers were provided in this data, so confirm them against the vendor bulletin. As an interim mitigation, restrict internet access to the Management Server IP address and configure Trusted Clients so SmartConsole connections are accepted only from known administrator addresses. Review management logs for unexpected logins, unauthenticated token issuance, or unfamiliar administrator sessions, and complete remediation per CISA BOD 26-04 given the KEV listing.

WordPress Core contains an interpretation-conflict flaw (CWE-436) in the REST API batch endpoint that causes route confusion, allowing requests to be dispatched to an unintended route. When chained with the author__not_in WP_Query SQL injection (CVE-2026-60137), this allows a remote, unauthenticated attacker to inject SQL and escalate to remote code execution. Any WordPress site running 6.9.x before 6.9.5 or 7.0.x before 7.0.2 is affected, with no privileges or user interaction required (CVSS 3.1: 9.8). Exploitation is confirmed in the wild: the issue was added to CISA's KEV on 2026-07-21, EPSS is 97.3% (100th percentile), and a public PoC is reportedly fueling mass scanning under the 'wp2shell' label.

Do: Upgrade immediately to WordPress 6.9.5 (for 6.9.x) or 7.0.2 (for 7.0.x), or later, which fixes both this flaw and the chained SQL injection CVE-2026-60137; prioritize internet-facing sites because exploitation is unauthenticated and being mass-scanned. Review web and REST API logs for suspicious batch requests, SQL errors, unexpected admin users, or modified files. Organizations in scope for CISA BOD 26-04 must apply the required mitigations per vendor instructions or discontinue use.

IBM Langflow OSS 1.0.0 through 1.10.0 contains an unauthenticated code-injection flaw (CWE-94) that can be chained into full remote code execution. An attacker with network access first calls /api/v1/auto_login, which mints a SUPERUSER token to any caller without authentication, then calls /api/v1/validate/code, which executes attacker-supplied code via exec() on the Langflow host. Successful exploitation yields full control of the affected deployment, with high impact on confidentiality, integrity, and availability (CVSS 3.1: 9.8, network-exploitable with no privileges or user interaction required). Anyone running IBM Langflow OSS 1.0.0-1.10.0 is affected, especially default deployments reachable from untrusted networks. CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-08-04, confirming active exploitation; EPSS estimates a 60.6% probability of exploitation within 30 days (99th percentile), and ransomware use is unknown.

Do: Upgrade IBM Langflow OSS to a release newer than 1.10.0 per IBM's ([email protected]) security advisory, as required under CISA's BOD 26-04 guidance for KEV entries; if mitigations are unavailable, discontinue use of the product per BOD 26-04. Until patched, restrict network access to the /api/v1/auto_login and /api/v1/validate/code endpoints (e.g., firewall rules or reverse-proxy controls) and avoid exposing the instance directly to the internet. Because exploitation is confirmed, review access logs for requests to these endpoints and signs of unauthenticated SUPERUSER token issuance or unexpected code execution.

Sangoma Switchvox SMB Edition 8.3 (build 104997) contains an unauthenticated SQL injection flaw (CWE-89) in its /pa endpoint, where the user-controlled PhoneIP value from XML input is concatenated directly into PostgreSQL queries without sanitization or parameterization. A single crafted request lets a remote, unauthenticated attacker execute arbitrary SQL statements against the backend PostgreSQL database, which can be escalated to remote code execution on the server. Any organization running the affected Switchvox SMB Edition build is exposed, especially appliances reachable from the internet. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV catalog on 2026-09-02, and researchers have observed attackers using it without credentials to deploy reverse shells and cryptocurrency miners.

Do: Identify all Switchvox SMB Edition deployments and verify the running build (affected: 8.3, build 104997), then upgrade to the patched release specified in Sangoma's advisory. If patching is delayed, restrict or remove internet exposure of the Switchvox web interface, including the /pa endpoint. Hunt for indicators of compromise such as unexpected reverse shells, new processes, or crypto-miner activity, as active exploitation is confirmed and the flaw is on CISA's KEV catalog, making it subject to BOD 26-04 patching guidance for federal stakeholders.

CVE-2026-15409 is a server-side request forgery (SSRF, CWE-918) in the Appliance Work Place interface of SonicWall SMA1000 series appliances. A remote, unauthenticated attacker can trigger the flaw over the network, causing the appliance to issue requests to attacker-influenced or unintended internal locations. Because the CVSS vector scores scope-changed impacts on confidentiality, integrity, and availability, the SSRF is assessed as capable of reaching sensitive internal services, and reporting indicates it is being used alongside a second SMA1000 zero-day in what may be an exploitation chain. Affected organizations are those running SMA1000 appliances, including SMA 6210, SMA 7210, and SMA 8200v models, which typically act as internet-facing remote-access/VPN gateways. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV on 2026-07-14, ransomware use is known, and EPSS assigns an 83.7% probability of exploitation within 30 days, though no public PoC is available.

Do: Apply SonicWall's SMA1000 firmware update per the vendor's instructions immediately, prioritizing appliances with the Appliance Work Place interface reachable from the internet. Because the flaw is in CISA's KEV with known ransomware use and may be chained with a second SMA1000 zero-day, hunt for signs of compromise (unexpected outbound or internal requests, anomalous VPN sessions, follow-on ransomware activity) and restrict internet exposure of the interface in the interim. Federal and critical-infrastructure operators must comply with CISA BOD 26-04, including cloud-service guidance, or discontinue use if mitigations are unavailable.

CVE-2026-50522 is a deserialization of untrusted data flaw (CWE-502) in Microsoft SharePoint Server that allows an unauthenticated attacker to send maliciously crafted serialized data over the network and execute code on the server, reflected in its 9.8 critical CVSS score with no privileges or user interaction required. Successful exploitation yields full remote code execution with high impact on confidentiality, integrity, and availability, giving attackers a foothold for follow-on actions such as data theft, lateral movement, or ransomware. Any organization running on-premises SharePoint Server is in scope, particularly deployments reachable from untrusted networks; the required action notes stakeholders must evaluate each asset's internet exposure under CISA BOD 26-04. The flaw is under active exploitation: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-07-22 and security news headlines describe it as a critical RCE exploited in the wild, with some reports referencing exploitation after a public proof-of-concept release and an authentication bypass. The structured record lists no public PoC as confirmed, but an EPSS of 84.6% (100th percentile) underscores a very high near-term exploitation likelihood.

Do: Apply Microsoft's security updates for SharePoint Server immediately per the vendor advisory, as required under CISA's KEV listing and BOD 26-04, and prioritize any SharePoint deployments that are internet-facing (federal/critical-infrastructure operators must follow BOD 26-04 timelines or discontinue unmitigated use). Until patched, restrict public access to SharePoint endpoints (VPN, firewall rules, or reverse proxy) and review IIS/application logs and running processes for signs of unauthenticated deserialization abuse. Because some reports reference an authentication bypass being chained, also verify authentication paths and monitor for follow-on attacker activity after patching.

Microsoft SharePoint Server contains a missing authentication for critical function vulnerability (CWE-306) that lets an unauthenticated attacker elevate privileges over a network without valid credentials. The flaw is triggered when the affected SharePoint function is accessed remotely without any authentication check, allowing an attacker to gain higher privileges than intended. Successful exploitation could enable an attacker to take elevated actions within the SharePoint environment, potentially leading to further compromise of the server and its data. All organizations running on-premises Microsoft SharePoint Server are potentially affected, though specific versions have not yet been enumerated by Microsoft or CISA. The vulnerability was added to CISA's Known Exploited Vulnerabilities catalog on 2026-07-14, indicating it is being actively exploited, and its EPSS score of 26.6% (98th percentile) reflects a high near-term exploitation risk.

Do: Apply Microsoft's security updates for SharePoint Server as soon as they are available, and check Microsoft's advisory for the specific affected version ranges once published. In the meantime, restrict network access to SharePoint servers, especially for internet-facing instances, and verify whether your environment falls under CISA BOD 26-04 requirements given the KEV listing. Monitor for updated guidance from Microsoft and CISA, as exploitation is confirmed and patching urgency is high.

CVE-2026-56291 is an unauthenticated unrestricted file upload flaw (CWE-434) in the Balbooa Forms extension for Joomla, affecting versions prior to 2.4.1. Because the upload functionality requires no authentication, any remote attacker who can reach a site running the extension can upload arbitrary files, including executable file types, to the web server. Uploaded executable files can subsequently be invoked on the server, resulting in full remote code execution with high impact on confidentiality, integrity, and availability. Any Joomla site running Balbooa Forms below version 2.4.1 is affected, particularly those whose upload functionality is reachable from the internet. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-07-10 after reportedly being exploited as a zero-day, and a public proof-of-concept write-up is available.

Do: Upgrade Balbooa Forms to version 2.4.1 or later immediately, as patching is the required action under CISA KEV/BOD 26-04 guidance. If upgrading is not immediately possible, restrict unauthenticated access to the extension's upload functionality at the web server or WAF layer and inspect upload directories for unexpected executable files that would indicate compromise. Review web logs for unauthenticated upload requests from unknown sources and treat any findings as potential RCE incidents.

CVE-2026-48282 is a path traversal vulnerability (CWE-22) in Adobe ColdFusion. It is triggered by crafted file-path input containing directory-traversal sequences that the application fails to constrain, allowing access outside the intended directory; per CISA this can escalate to arbitrary code execution in the context of the current user. Successful exploitation could give an attacker the ability to run code on the ColdFusion host under the ColdFusion service account, a common foothold for further network compromise. All organizations running affected Adobe ColdFusion releases, particularly internet-facing instances, are in scope; the specific affected version ranges have not been detailed in the available data. The flaw is already being exploited in the wild: it was added to CISA's Known Exploited Vulnerabilities catalog on 2026-07-07 and carries a 42.4% EPSS probability of exploitation within 30 days (99th percentile), though no public PoC is known and ransomware use is unconfirmed.

Do: Inventory all Adobe ColdFusion deployments, prioritizing internet-facing servers, and apply the vendor patch per Adobe's security advisory since the affected version ranges are not yet specified in this data. Federal agencies must patch or apply mitigations in accordance with CISA BOD 26-04 within the KEV deadline or discontinue use if mitigations are unavailable. Until patched, restrict external access to ColdFusion instances and consider WAF/IPS rules blocking directory-traversal sequences in file-path parameters.

Joomlack Page Builder, a page-builder extension for the Joomla CMS from the Joomlack vendor, contains an improper access control flaw (CWE-284) that permits unauthenticated arbitrary file upload to affected sites. An unauthenticated remote attacker can abuse the upload functionality to place attacker-controlled files, typically executable script files, on the web server and then request them to achieve remote code execution. Successful exploitation yields code execution under the web server's privileges, enabling full compromise of the website and potentially the underlying hosting account or server; ransomware use has not been confirmed. Any Joomla deployment with the affected extension installed is potentially exposed, with internet-facing sites at greatest risk, and CISA has not published specific affected version ranges. The flaw was added to the CISA KEV catalog on 2026-07-07, indicating confirmed in-the-wild exploitation, and it carries a high exploitation likelihood (EPSS 30.4%, 98th percentile), although no public proof-of-concept or detailed technical write-up is known.

Do: Inventory Joomla sites for the Joomlack Page Builder extension and apply the vendor's fix as soon as it is released, following the CISA required action and BOD 26-04 guidance; if mitigations are unavailable, remove, disable, or restrict the extension - particularly on internet-exposed or cloud-hosted instances - or discontinue use per BOD 26-04. Until patched, review upload directories for unexpected executable files (e.g., potential webshells) and check access logs for unauthenticated upload requests, and limit direct web access to upload paths where feasible.

CVE-2026-49869 is a critical (CVSS 3.1: 10.0) authentication bypass in the open-source Kestra event-driven orchestration platform: the AuthenticationFilter exempts the public configuration endpoint from Basic Auth using a suffix match (request paths ending in "/configs") rather than an exact path comparison. As a result, an unauthenticated remote attacker can call any API URL whose final path segment is "configs", which is enough to create and execute arbitrary workflows without credentials. Because Kestra ships with script execution plugins (plugin-script-shell, plugin-script-python, etc.) enabled by default, this directly yields unauthenticated remote code execution as root inside the Kestra worker container. All Kestra OSS deployments prior to 1.0.45 and 1.3.21 are affected, with the greatest risk for instances whose API is reachable from the internet or untrusted networks. The flaw is being actively exploited: CISA added it to the KEV catalog on 2026-09-02 (EPSS 1.9%, percentile 79), and headlines covering the KEV batch report attackers deploying reverse shells and crypto miners.

Do: Upgrade to Kestra 1.0.45 (for the 1.0.x line) or 1.3.21 (for the 1.3.x line), or later releases that incorporate the fix. If immediate patching is not possible, restrict network access to the Kestra API (firewall/ACL or a reverse proxy that enforces authentication for all paths, including any ending in /configs). Given active exploitation, audit instances for signs of compromise such as unexplained workflows, reverse shells, or cryptomining processes in worker containers; federal agencies must patch per CISA BOD 26-04 timelines.

Joomlic's iCagenda event-management extension for Joomla contains an unrestricted file-upload flaw (CWE-434) in its file attachment feature, exploitable over the network without authentication or user interaction (CVSS 4.0 score 10.0). Because the extension accepts arbitrary file types, an attacker can upload a malicious PHP file through the attachment feature and have the web server execute it as PHP code. Successful exploitation gives unauthenticated attackers remote code execution on the affected Joomla site, which typically leads to full site or web-server compromise. Any Joomla installation running the iCagenda extension is affected; the available advisory data specifies no affected or fixed version range, so no version numbers can be stated. The flaw is being exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-07-10 (reportedly exploited as a zero-day, with ransomware use currently unknown), public proof-of-concept code is available, and EPSS assigns roughly a 20% probability of exploitation within 30 days.

Do: Joomla administrators running iCagenda should update to the latest release published by Joomlic (no specific fixed version is stated in the available data) and, per the KEV required action, apply vendor mitigations in accordance with CISA BOD 26-04, prioritizing internet-exposed instances. Until patched, restrict or disable the file-attachment upload feature (e.g., prevent PHP execution/uploads in the attachments directory) and review web server logs and upload directories for unexpected .php files indicating prior compromise. Given confirmed in-the-wild exploitation reportedly predating disclosure, assume potential compromise and follow CISA's forensics triage requirements where applicable.

CVE-2026-48908 is an unrestricted upload of files with dangerous types (CWE-434) in the SP Page Builder extension for Joomla developed by JoomShaper/Ollyo. An unauthenticated remote attacker can submit arbitrary files, including PHP files, to the vulnerable upload functionality, and the web server subsequently executes the uploaded PHP. Successful exploitation therefore results in full remote code execution on the hosting server with the privileges of the web service, giving the attacker control over the Joomla site and its data (CVSS 4.0 base score: 10.0, critical). Any Joomla site running SP Page Builder is affected; the available data does not specify affected or fixed version ranges. The flaw is being actively exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-07-07, and EPSS assigns a 14.8% probability of exploitation within 30 days (96th percentile); no public proof-of-concept is known.

Do: Upgrade SP Page Builder to the latest release published by Ollyo/JoomShaper and follow the vendor advisory (no specific fixed version is provided in this data); federal agencies must apply mitigations per CISA's BOD 26-04 timelines and the KEV required action. Until patched, restrict or firewall unauthenticated access to SP Page Builder upload endpoints and review web-access logs and upload directories for recently dropped PHP files or webshells, since the flaw is confirmed exploited in the wild.

PTC Windchill and FlexPLM contain an improper input validation flaw (CWE-20) with an associated deserialization of untrusted data weakness (CWE-502) that allows an unauthenticated, remote attacker to execute arbitrary code by sending a malicious request over the network. An attacker who can reach a vulnerable Windchill or FlexPLM server can run arbitrary code on it, potentially gaining a foothold for lateral movement; CISA notes the flaw is being used in ransomware campaigns. All organizations running PTC Windchill or FlexPLM are affected, and the available data does not specify affected version ranges. The vulnerability was added to CISA's Known Exploited Vulnerabilities catalog on 2026-06-25 with known ransomware use, and EPSS assigns a 40.6% probability of exploitation within 30 days (99th percentile). No CVSS score or public proof-of-concept is available yet, but the KEV listing confirms exploitation in the wild.

Do: Apply the fixes in PTC's security advisory for CVE-2026-12569 to both Windchill and FlexPLM as soon as possible, prioritizing internet-facing instances, and comply with the CISA KEV required action under BOD 26-04 (patch within the required window or discontinue use if mitigations are unavailable). Until patched, restrict network exposure of Windchill/FlexPLM servers and hunt for signs of exploitation or ransomware precursor activity; the available data does not list specific patched versions, so defer to PTC's advisory.

CVE-2026-48558 is an authentication bypass (CWE-347, improper verification of cryptographic signature) in the SimpleHelp remote access/support platform's OpenID Connect (OIDC) login flow, where submitted identity tokens are accepted without verifying their signature. It is triggered when OIDC authentication is configured: a remote, unauthenticated attacker can submit a forged token containing arbitrary identity claims and obtain a fully authenticated technician session, and in some configurations this also bypasses multi-factor authentication. Related reporting describes a path from this bypass to remote code execution. Only SimpleHelp deployments using OIDC-based (e.g., SSO) authentication are affected; deployments relying on local SimpleHelp accounts are not described as affected. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-06-29, confirming exploitation in the wild, with a 30% EPSS probability of exploitation within 30 days and no public proof-of-concept known.

Do: Update SimpleHelp to the latest release per vendor instructions, prioritizing any internet-facing server (CISA KEV listing means federal agencies must act under BOD 26-04). Until patched, restrict access to the SimpleHelp web login to trusted management networks (VPN/firewall) or temporarily switch from OIDC to local-account authentication with MFA. Verify whether OIDC is enabled on each instance and review technician login logs for sessions created with unusual or unexpected identity claims.

CVE-2026-20253 is a critical (CVSS 9.8) missing-authentication flaw (CWE-306) in the PostgreSQL sidecar service endpoint of Splunk Enterprise, which lacks authentication controls. Any unauthenticated user who can reach the endpoint over the network can invoke file operations without credentials, creating or truncating arbitrary files on the host; public research (watchTowr) and news coverage describe this leading to pre-authentication remote code execution. The flaw affects Splunk Enterprise 10.2 versions below 10.2.4 and 10 versions below 10.0.7, while versions 9.4 and earlier are not affected. Exploitation is confirmed: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-06-18, media reports indicate it is under active attack, and EPSS assigns a 96.9% probability of exploitation within 30 days.

Do: Upgrade to Splunk Enterprise 10.2.4 (10.2 track) or 10.0.7 (10 track) or later; Splunk Enterprise 9.4 and earlier are unaffected. If you cannot upgrade immediately, disable the PostgreSQL sidecar service per vendor guidance and ensure the endpoint is not reachable from untrusted networks. As a KEV entry, federal agencies must apply vendor mitigations in line with BOD 26-04 by the CISA deadline; audit whether the PostgreSQL sidecar service is enabled and whether it is exposed to the internet.

CVE-2026-25089 is an OS command injection flaw (CWE-78) in Fortinet FortiSandbox caused by improper neutralization of special elements in OS commands, allowing an unauthenticated attacker to execute unauthorized commands by sending specifically crafted HTTP requests to the product. The flaw is network-exploitable with no privileges or user interaction required (CVSS 3.1 score of 9.8), meaning any reachable instance — hardware/VM appliance, FortiSandbox Cloud, or FortiSandbox PaaS — is exposed to system-level command execution. Successful exploitation carries high impact to confidentiality, integrity, and availability on the sandbox itself and can serve as a foothold into the surrounding network. Organizations running FortiSandbox 5.0.0–5.0.5, 4.4.0–4.4.8, or 4.2 (all versions), as well as FortiSandbox Cloud 5.0.4–5.0.5 and FortiSandbox PaaS 5.0.4–5.0.5, are affected. The vulnerability is being actively exploited in the wild: CISA added it to the KEV catalog on 2026-07-16, EPSS assigns a 76.1% probability of exploitation within 30 days (100th percentile), and news coverage describes FortiSandbox bugs under active attack, though no public proof-of-concept is known.

Do: Upgrade FortiSandbox to a release beyond the affected ranges — newer than 5.0.5, 4.4.8, and 4.2 — and update FortiSandbox Cloud and PaaS beyond 5.0.5, following Fortinet's PSIRT advisory for the exact fixed versions (not specified in this data). Until patched, restrict the FortiSandbox management interface from direct internet exposure and review appliance logs for signs of command-injection exploitation. Organizations subject to CISA's KEV requirements must apply vendor mitigations per BOD 26-04 timelines or discontinue cloud use of the product if mitigations are unavailable.

Progress Kemp LoadMaster, the application delivery controller/load balancer sold by Progress Software (formerly Kemp), contains an unauthenticated OS command injection flaw (CWE-77) in its API: unsanitized input sent to multiple command endpoints allows arbitrary operating-system commands to be executed on the appliance. Because the affected endpoints require no authentication, any remote attacker with network access to the appliance's API or management interface can trigger the bug directly; public research by WatchTowr describes it as a pre-authentication RCE chain (involving uninitialized memory/quote handling) that can yield root-level command execution. Successful exploitation gives an attacker full control of the appliance, consistent with the Critical 9.8 CVSS 3.1 score (network-exploitable, no privileges or user interaction, high impact on confidentiality, integrity and availability). Organizations running Progress Kemp LoadMaster appliances are affected, especially those where the management or API interface is reachable from the internet. Exploitation is confirmed and ongoing: CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-08-07 after 792 reported exploit attempts, and EPSS assigns a 99.6% probability of exploitation within 30 days.

Do: Upgrade LoadMaster to the fixed release identified in Progress's security advisory (fixed version numbers are not specified in this data). Until patched, restrict the LoadMaster API/management interface to trusted networks or VPN access, and review appliance logs for signs of unexpected command execution given confirmed in-the-wild exploitation. Because the flaw is on CISA's KEV catalog, US federal agencies must apply mitigations per BOD 26-04 by the required deadline — or discontinue use of the product if mitigations are unavailable — and evaluate each asset's internet exposure.

Oracle E-Business Suite contains a critical improper privilege management flaw (CVE-2026-46817) in the File Transmission component of Oracle Payments, affecting versions 12.2.3 through 12.2.15. The flaw is easily exploitable: an unauthenticated attacker with network access over HTTP can trigger it, with no credentials or user interaction required. Successful exploitation results in takeover of Oracle Payments, with high confidentiality, integrity, and availability impact (CVSS 3.1 9.8). Organizations running the affected E-Business Suite releases — especially those exposing the Payments/File Transmission interface to untrusted networks — are in scope. The issue was added to CISA's Known Exploited Vulnerabilities catalog on 2026-07-15, researchers have observed exploitation in the wild, and EPSS assigns a 13% probability of exploitation within 30 days (96th percentile).

Do: Apply the remediation provided in Oracle's security advisory for CVE-2026-46817 to all Oracle E-Business Suite 12.2.3–12.2.15 environments running Oracle Payments, and in the meantime restrict HTTP/network access to the File Transmission component. Because the flaw is being actively exploited, review EBS/Payments access logs for unauthenticated requests and anomalous file-transmission activity to check for compromise. Federal agencies must apply mitigations in line with CISA BOD 26-04 timelines or discontinue use of the product if mitigations are unavailable.

CVE-2026-34910 is an improper input validation flaw (CWE-20) in Ubiquiti UniFi OS that allows command injection on affected gateways and network video recorders. A malicious actor with network access to the device can send crafted, unvalidated input that triggers arbitrary command execution, with no privileges or user interaction required (CVSS 3.1 base score 10.0, network vector, scope changed). Successful exploitation grants full control of the device — high confidentiality, integrity, and availability impact — and can serve as a foothold into the attached network. Affected products span the UniFi gateway and recording line: UniFi OS Server, Cloud Gateway Industrial, Dream Machine/Pro/Special Edition/Pro Max, Enterprise Fortress Gateway, Dream Wall, Dream Router and Dream Router 7, UniFi Express 7, and the UniFi Network Video Recorder. CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-06-23, public reporting describes in-the-wild exploitation being used to build a Mirai botnet, and EPSS estimates an 87.5% chance of exploitation within 30 days.

Do: Upgrade all listed UniFi OS devices to the fixed firmware in Ubiquiti's June 2026 security advisory (consult the vendor advisory for exact fixed versions per product), and per CISA BOD 26-04 patch within the required window or discontinue use of affected cloud-reachable assets. Restrict device management interfaces (UniFi Network UI, SSH, API) to trusted networks and audit internet-facing gateways for signs of compromise, including Mirai botnet traffic or unexpected outbound connections.

A double-free memory-corruption flaw (CWE-415) in the Microsoft Windows Internet Key Exchange (IKE) service extension allows a remote, unauthenticated attacker to trigger the bug with crafted network traffic, with no privileges or user interaction required. Successful exploitation yields remote code execution with full system impact, reflected in the critical 9.8 CVSS score (high confidentiality, integrity, and availability). The vulnerable IKE component is present in Windows 10 (1607, 1809, 21H2, 22H2), Windows 11 (23H2, 24H2, 25H2, 26H1), and Windows Server 2016, 2019, and 2022 (including 23H2), which ship it as a built-in feature. CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-08-18, and security reporting confirms it is being actively exploited in the wild, though ransomware use is not yet confirmed. No public proof-of-concept is known, but the high EPSS score (72.7%, 99th percentile) signals a very strong likelihood of imminent or ongoing exploitation.

Do: Apply Microsoft's security updates for CVE-2026-33824 to all affected Windows 10, Windows 11, and Windows Server releases, prioritizing internet-exposed systems where IKE/VPN is reachable (UDP 500/4500), per BOD 26-04 requirements. Organizations unable to patch promptly should restrict or discontinue use of exposed IKE/VPN services on affected hosts until updated. Triage VPN endpoints and remote-access servers for crashes or suspicious IKE traffic given confirmed in-the-wild exploitation.

CVE-2026-39808 is an OS command injection flaw (CWE-78) in Fortinet FortiSandbox versions 4.4.0 through 4.4.8, caused by improper neutralization of special elements passed to OS commands. The vulnerability is network-reachable, requires no privileges or user interaction (CVSS 3.1: 9.8, AV:N/AC:L/PR:N/UI:N), though CISA's description does not specify the exact entry point that a remote unauthenticated attacker abuses to trigger it. Successful exploitation lets the attacker execute unauthorized code or commands on the appliance, with high impact to confidentiality, integrity, and availability. Any organization running FortiSandbox 4.4.0-4.4.8 is affected; these sandboxing appliances are typically deployed as add-ons to enterprise FortiGate security estates. The flaw was added to CISA's KEV on 2026-07-16, and press coverage describes critical FortiSandbox bugs coming under active attack, so in-the-wild exploitation should be assumed.

Do: Upgrade all FortiSandbox appliances out of the affected 4.4.0-4.4.8 range to a fixed release per Fortinet's advisory, prioritizing internet-exposed units and complying with the CISA KEV required action (added 2026-07-16) and BOD 26-04 guidance. Until patched, restrict network access to the appliance's management and analysis interfaces and triage for signs of command execution such as unexpected processes or outbound connections. Confirm the specific fixed 4.4.x build in Fortinet's PSIRT advisory before scheduling upgrades.

CVE-2025-67038 is an OS command injection flaw (CWE-78) in the HTTP RPC module of Lantronix EDS5000 series device servers, with firmware 2.1.0.0R3 confirmed affected. When a login attempt fails, the module writes a log entry by building a shell command that directly concatenates the username from the request without any sanitization, so an attacker who sends a crafted username in an authentication request gets their commands appended to it. Because the log-writing command runs as root, an unauthenticated, network-reachable attacker gains full command execution with the highest privileges on the device. Any organization running network-exposed Lantronix EDS5000 device/console servers (EDS5008, EDS5016, EDS5032, and the G526/G527-series variants) is affected. CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2026-06-23 and reports it is being actively exploited; the EPSS score of 19.3% (97th percentile) reflects a high near-term exploitation risk.

Do: Upgrade EDS5000-series firmware to a patched release per Lantronix's guidance, since no fixed version is specified in the available data and 2.1.0.0R3 is confirmed vulnerable; if patching is not yet possible, restrict HTTP access to the device's management interface at the network level. Federal agencies must apply vendor mitigations per CISA BOD 26-04 requirements following the 2026-06-23 KEV listing. Check device logs and configs for signs of compromise, since successful injection yields root-level command execution.

CVE-2026-20079 is an authentication bypass (CWE-288) in the web interface of Cisco Secure Firewall Management Center (FMC) Software, caused by an improper system process created at boot time. An unauthenticated, remote attacker can exploit it by sending crafted HTTP requests to the FMC web interface, which allows the execution of script files and commands on the device. A successful exploit grants the attacker root access to the underlying operating system, giving full control of the management platform (CVSS 3.1: 10.0, network-exploitable, no privileges or user interaction required, scope changed). The flaw affects Cisco Secure Firewall Management Center (FMC) and Security Cloud Control (SCC) Firewall Management deployments. Cisco has confirmed the vulnerability is being exploited in active attacks, it carries a 35.9% EPSS score (98th percentile), and CISA added it to the Known Exploited Vulnerabilities catalog on 2026-09-09.

Do: Upgrade FMC (and SCC Firewall Management tenants) to the fixed release specified in Cisco's advisory, prioritizing internet-exposed or externally reachable management interfaces; CISA KEV action applies to federal agencies under BOD 26-04. Until patching, restrict FMC web interface access to trusted management networks and VPNs and check devices for signs of exploitation such as unexpected script execution, unfamiliar processes, or root-level changes. Triage per CISA's Forensics Triage Requirements if compromise is suspected.

CVE-2026-0770 is an unauthenticated remote code execution vulnerability in Langflow, an open-source visual builder for LLM and AI agent workflows. The flaw, categorized as CWE-829 (inclusion of functionality from an untrusted control sphere), resides in how the exec_globals parameter supplied to the validate endpoint is handled, allowing code or resources from an untrusted control sphere to be included and executed. A remote attacker with no credentials can send a crafted request to that endpoint and execute arbitrary code in the context of root on the affected installation. Any deployment of an affected Langflow version is exposed, with internet-facing self-hosted or containerized instances at greatest risk. The issue was disclosed through Trend Micro's Zero Day Initiative (ZDI-CAN-27325) and was added to CISA's Known Exploited Vulnerabilities catalog on 2026-07-21, confirming active in-the-wild exploitation; no public proof-of-concept is known.

Do: Apply the vendor's patched Langflow release and any prescribed mitigations per CISA guidance; because exploitation requires no authentication and executes as root, prioritize internet-exposed instances immediately (EPSS is high at 63.4%). Per BOD 26-04, if mitigations or updates are unavailable for a given deployment, discontinue use of the product. Review access logs for unexpected unauthenticated requests to the validate endpoint containing crafted exec_globals parameters, and restrict network exposure of Langflow instances until patched.

CVE-2026-21962 is an improper access control flaw (CWE-284) in Oracle HTTP Server and the Oracle WebLogic Server Proxy Plug-in (components: the plug-in for Apache HTTP Server and the plug-in for IIS), part of Oracle Fusion Middleware. An unauthenticated attacker with network access via HTTP can trivially exploit it, and the scope-change designation means a successful attack can significantly impact additional products beyond the plug-in itself. The attacker gains unauthorized access to critical data (potentially all accessible data) as well as the ability to create, delete, or modify critical data, reflected in the maximum CVSS 10.0 score with high confidentiality and integrity impacts and no availability impact. Organizations running the affected versions - 12.2.1.4.0, 14.1.1.0.0 and 14.1.2.0.0 for Oracle HTTP Server and the Apache plug-in, and 12.2.1.4.0 only for the IIS plug-in - especially those with internet-facing Apache/IIS/OHS front ends proxying WebLogic applications, are exposed. The flaw is being actively exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-24, and EPSS assigns a 42% probability of exploitation within 30 days, though no public proof-of-concept is known.

Do: Apply the fixes from Oracle's January 2026 quarterly update (advisory AV26-042) or later for Oracle HTTP Server and the WebLogic Server Proxy Plug-in on all affected versions - 12.2.1.4.0, 14.1.1.0.0 and 14.1.2.0.0 (IIS plug-in affected at 12.2.1.4.0 only). Prioritize internet-facing OHS, Apache and IIS front ends per CISA BOD 26-04 and the KEV required actions, and where patching is delayed, restrict HTTP access to trusted networks and review logs for signs of unauthorized data access or modification.

CVE-2025-25249 is a heap-based buffer overflow (CWE-122/CWE-787) in Fortinet FortiOS, FortiSwitchManager, and FortiSASE that allows an attacker to execute unauthorized code or commands. It is triggered by sending specially crafted packets to an affected device, causing an out-of-bounds write in heap memory that can be leveraged for code execution. Successful exploitation gives attackers command execution on the appliance; in observed intrusions against FortiGate firewalls, attackers have deployed custom Node.js malware and a post-exploitation RAT dubbed PivotC2. Any organization running the affected Fortinet products is at risk, with internet-facing FortiGate firewalls the primary concern. The flaw was added to CISA's KEV on 2026-09-09, confirming active exploitation in the wild (ransomware use unknown); no public PoC is known.

Do: Upgrade FortiOS, FortiSwitchManager, and FortiSASE in accordance with Fortinet's advisory (specific fixed versions are not listed in the available data), prioritizing internet-exposed FortiGate firewalls per CISA KEV and BOD 26-04 timelines. Hunt for signs of compromise, including custom Node.js malware and the PivotC2 RAT, on FortiGate devices, and review exposure and access logs for admin/SSL-VPN interfaces. If patching is not possible, apply vendor-recommended mitigations or, per BOD 26-04, discontinue use of the exposed product.
