CVE-2026-85706
Unauthenticated Path Traversal Arbitrary File Read in GitLab CE/EE

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-2026-60004
Unauthenticated RCE in Gitea via diffpatch API Git Hook Injection

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.

Unauthenticated SSRF in MLflow Exposes Cloud Credentials and Secrets

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-2026-73570
Unauthenticated OS Command Injection RCE in Synacor Zimbra Collaboration Suite

CVE-2026-73570 is an OS command injection vulnerability (CWE-78) in Synacor Zimbra Collaboration Suite (ZCS) before 10.1.20, caused by improper sanitization of untrusted input during SNMP notification processing. It is triggered when the optional zimbra-snmp package is installed and SNMP notifications are enabled: an unauthenticated attacker sends specially crafted SMTP requests that the flawed notification path turns into execution of arbitrary operating system commands. Successful exploitation runs commands as the Zimbra user, giving attackers control of the mail server's service account with high confidentiality and integrity impact across the host. Only ZCS deployments running the optional SNMP component with notifications enabled are vulnerable; other Zimbra installs are not exposed to this specific flaw. The flaw is under active exploitation: CISA added it to the KEV catalog on 2026-08-21, Poland's CERT has warned of in-the-wild attacks, unpatched Zimbra servers are reported compromised, and two public proof-of-concept exploits exist.

Do: Upgrade to Zimbra Collaboration Suite 10.1.20 or later per vendor instructions; as an interim mitigation, disable SNMP notifications or remove the zimbra-snmp package on hosts that do not need it. Federal operators must satisfy the CISA KEV/BOD 26-04 requirement, and all administrators of internet-facing Zimbra servers should hunt for signs of compromise (unexpected processes or persistence under the zimbra user) since unpatched systems are already being exploited.

Unauthenticated SQL Injection in Metabase Grants Admin Access

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.

Authentication Bypass in Apple macOS Screen Sharing

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.

CVE-2026-18577
Authentication Bypass and Account Takeover in N-able N-central (Incomplete Patch)

CVE-2026-18577 is an authentication bypass (CWE-288) in N-able's N-central RMM platform caused by an incomplete patch for the earlier vulnerability CVE-2026-18556. Because the original fix can be bypassed via an alternate path or channel, a remote, unauthenticated attacker needs no privileges or user interaction, though the attack requires meeting exploit-specific conditions (high attack complexity, CVSS 4.0: 8.2 High). Successful exploitation lets the attacker bypass authentication and take over N-central accounts, gaining high-impact access to the management console with limited direct effects on downstream services. All N-central versions through 2026.3.1 are affected. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV on 2026-08-03, EPSS estimates a 54.1% chance of exploitation within 30 days (99th percentile), and news reports say attackers kept exploiting it even as N-able shipped successive hotfixes; ransomware use is currently unknown.

Do: Upgrade N-central to a fixed release or hotfix newer than 2026.3.1 following N-able's advisory — the vendor has issued multiple successive hotfixes for this and related N-central flaws, so verify you are on the latest build. Because the flaw is on CISA's KEV, federal and BOD 26-04-bound organizations must apply vendor mitigations promptly or discontinue use of the product if patching is unavailable. Limit internet exposure of N-central portals and review accounts for signs of takeover or unauthorized access.

CVE-2026-18556
Authentication Bypass (Alternate Path/Channel) in N-able N-central

N-able's N-central RMM platform contains an authentication bypass (CWE-288) in which an alternate path or channel allows requests to skip the normal authentication check. An unauthenticated attacker can trigger it by sending requests through that alternate path without valid credentials, gaining unauthorized access to the N-central management interface; because N-central is remote monitoring and management software run by managed service providers, such access can expose management functions across downstream customer environments. N-able N-central deployments are affected; the available data does not specify affected version ranges or fixed builds. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-08-04, confirming exploitation in the wild, with a high EPSS of 40.2% (99th percentile), no CVSS score yet, no public PoC, and undetermined ransomware use; related reporting describes a recent string of N-central hotfixes, including fixes for unauthenticated remote code execution.

Do: Apply N-able's hotfix for N-central immediately per the vendor's instructions, since the flaw is in CISA KEV and BOD 26-04 applies (for cloud-hosted N-central, apply mitigations per BOD 26-04 or discontinue use if mitigations are unavailable). Until patched, restrict internet exposure of the N-central server to trusted management networks and review authentication logs for unexpected access, following CISA's forensics triage guidance.

CVE-2026-59310
Unauthenticated Path Traversal RCE in Broadcom VMware vCenter Server Syslog

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.

Hard-Coded Password Vulnerability in Cisco Secure Firewall Management Center

Cisco Secure Firewall Management Center (FMC), formerly Firepower Management Center, contains a use of hard-coded password vulnerability (CWE-259) that allows an unauthenticated, remote attacker to log in to an affected system. By authenticating with the built-in hard-coded credentials for a low-privileged account, the attacker can gain access to sensitive data within the impacted systems. Any organization running an affected Cisco FMC deployment is exposed, particularly where the management interface is reachable from untrusted networks. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-07-29, indicating active exploitation in the wild, and related reporting describes active exploitation of FMC vulnerabilities. No CVSS score or public proof-of-concept is yet available, but EPSS assigns a 9.8% probability of exploitation within 30 days (95th percentile).

Do: Upgrade FMC to the fixed release per Cisco's security advisory, as no specific fixed version is provided in this data. Until patched, restrict access to the FMC management interface, audit recent logins against the affected low-privileged accounts, and rotate or remove any hard-coded credentials.

Unauthenticated Deserialization RCE in JetBrains TeamCity On-Premises

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.

Authentication Bypass in Check Point SmartConsole Grants Full Admin Access

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.

Unauthenticated RCE Chain in IBM Langflow OSS 1.0.0-1.10.0

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.

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.

Path Traversal Leading to RCE in Adobe ColdFusion

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.

Improper Access Control Enables Unauthenticated RCE in Joomlack Page Builder

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.

Unauthenticated File-Upload RCE in Joomlic iCagenda for Joomla

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.

Unauthenticated File Upload RCE in JoomShaper SP Page Builder for Joomla

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.

Unauthenticated RCE in PTC Windchill and FlexPLM

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).

Authentication Bypass via Forged OIDC Tokens in SimpleHelp

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.

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.

Unauthenticated OS Command Injection RCE in Fortinet FortiSandbox

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.

Unauthenticated OS Command Injection RCE in Progress Kemp LoadMaster

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.

SSRF in Cisco Unified Communications Manager Enables Root Escalation

An unauthenticated server-side request forgery (SSRF) flaw exists in Cisco Unified Communications Manager (Unified CM) and Unified CM Session Management Edition (Unified CM SME), caused by improper input validation of specific HTTP requests. An attacker triggers it by sending a crafted HTTP request to the device's WebDialer service, which must be enabled for exploitation (it is disabled by default). Successful exploitation lets the attacker write files to the underlying operating system, which can later be used to elevate privileges to root — the reason Cisco assigned a Critical Security Impact Rating despite the 8.6 (High) CVSS base score. Organizations running affected Unified CM or Unified CM SME deployments, particularly those with WebDialer enabled and reachable from untrusted networks, are exposed. The flaw is being exploited in the wild: public exploit references appeared in mid-June 2026, and CISA added it to the Known Exploited Vulnerabilities catalog on 2026-06-25, with EPSS indicating an ~88% probability of exploitation within 30 days.

Do: Upgrade affected Unified CM and Unified CM SME deployments to the fixed release cited in Cisco's advisory (specific version not provided in this dataset), prioritizing internet-exposed systems per CISA BOD 26-04 requirements.

HTTP Request Smuggling in Kludex Starlette (CVE-2026-48710)

Kludex Starlette prior to version 1.0.1 did not validate the HTTP Host request header before using it to reconstruct request.url, an inconsistency classified as HTTP request/response smuggling (CWE-444). Because routing operates on the raw ASGI scope path while request.url is rebuilt from the unvalidated Host header, an attacker can send a malformed Host header so that request.url.path differs from the path the router actually processed. Any middleware or endpoint that enforces security restrictions based on request.url rather than the raw scope path can then be tricked into approving requests that should have been blocked, bypassing those controls. All Starlette deployments below 1.0.1 are affected, both direct users and downstream products that bundle the library, including Red Hat offerings such as Ansible Automation Platform, OpenShift AI, OpenShift Lightspeed, Satellite, AI Inference Server, Migration Toolkit for Applications, and Enterprise Linux AI. CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-09-02, confirming active exploitation; related reporting describes attackers deploying reverse shells and crypto miners, and EPSS ranks it in the 98th percentile with a 36.3% probability of exploitation within 30 days.

Do: Upgrade Starlette to 1.0.1 or later, which validates the Host header against RFC 9112/RFC 3986 grammar and falls back to scope['server'] for malformed values, and apply the corresponding Red Hat updates for each bundled product listed above. Until patched, review middleware and endpoints that enforce security decisions from request.url and validate or pin the Host header at your reverse proxy or load balancer.

CVE-2026-45659 is a deserialization-of-untrusted-data vulnerability (CWE-502) in Microsoft SharePoint Server in which an authorized (authenticated, low-privilege) attacker can submit crafted serialized data over the network, with no user interaction required, to execute code on the server. Successful exploitation carries high impact on confidentiality, integrity, and availability within the SharePoint service context, giving attackers a foothold for follow-on activity, and CISA notes that ransomware use is known. Organizations running on-premises Microsoft SharePoint Server are affected; the source data lists no specific version ranges, and the CPE scope (sharepoint server) points to the on-premises product rather than the Microsoft-managed SharePoint Online service. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-07-01 after active exploitation, and its EPSS score of 76.1% (100th percentile) indicates a high probability of near-term exploitation.

EncryptInterceptor Bypass Exposes Cluster Traffic in Apache Tomcat

CVE-2026-34486 is a missing-encryption vulnerability in Apache Tomcat in which the EncryptInterceptor, the component that encrypts Tomcat cluster communication, can be bypassed in a fail-open manner; the flaw was introduced as a regression by the fix for CVE-2026-29146. It affects Tomcat 11.0.20, 10.1.53 and 9.0.116, and is triggered when cluster communication is expected to be encrypted: an attacker positioned on the network path between cluster nodes receives inter-node traffic in cleartext. By reading that unencrypted traffic, the attacker can obtain sensitive data such as session payloads, potentially enabling session theft and authentication bypass as indicated by related reporting. Only deployments running the affected point releases with the EncryptInterceptor in use are impacted, including Tomcat shipped in Red Hat JBoss Web Server and Red Hat Enterprise Linux channels. The flaw is being actively exploited: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-04, EPSS places 30-day exploitation probability at 98.6%, though no public proof-of-concept is known and ransomware use is unconfirmed.

Do: Upgrade Apache Tomcat to 11.0.21, 10.1.54 or 9.0.117, and apply the corresponding Red Hat JBoss Web Server / Enterprise Linux updates when published. Audit Tomcat cluster configurations for EncryptInterceptor usage, and until patched restrict or encrypt the network segment carrying inter-node cluster traffic. Because the flaw is in CISA's KEV catalog, federal agencies must patch per BOD 26-04 timelines and should review cluster nodes for signs of session data interception.

CVE-2025-67038
Unauthenticated Root Command Injection in Lantronix EDS5000 Device Servers

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
Authentication bypass to root access in Cisco Secure Firewall Management Center

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.

CVE-2025-68686
Unauthenticated Info-Exposure Bypass of Symlink Patch in Fortinet FortiOS

CVE-2025-68686 is a sensitive-information-exposure flaw (CWE-200) in Fortinet FortiOS that allows a remote, unauthenticated attacker to bypass the vendor's patch for the symbolic-link (symlink) persistency mechanism seen in some post-exploitation cases. It is triggered by crafted HTTP requests sent to a device that has already been compromised through another vulnerability at the filesystem level, for example where symlinks were planted to maintain access to files. By bypassing the patch, the attacker can keep retrieving sensitive information from an otherwise remediated FortiGate device. Any organization running an affected FortiOS release is potentially affected; the CISA data does not enumerate specific versions, so administrators should consult Fortinet's advisory for the affected branches. The flaw was added to CISA's KEV catalog on 2026-07-27, confirming real-world exploitation, and EPSS assigns a 29.6% probability of exploitation within 30 days (98th percentile), with ransomware use currently unknown.

Do: Patch affected FortiOS devices per Fortinet's current advisory, following BOD 26-04 timelines for federal agencies (apply mitigations per vendor instructions or discontinue use where mitigations are unavailable). Because this flaw defeats the earlier symlink-persistence fix, re-check previously remediated devices for residual or recreated symlinks and hunt for indicators of prior filesystem-level compromise, such as unexpected symlinks and anomalous SSL-VPN activity. Review logs for crafted HTTP requests and prioritize internet-facing FortiGate assets for patching and triage.

Unauthenticated Remote Code Execution in Langflow validate Endpoint

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
Unauthenticated Access Control Bypass in Oracle HTTP Server and WebLogic Proxy Plug-in

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).

CVE-2025-62593
Actively Exploited Browser-Based RCE in Ray AI Compute Engine

Ray, the open-source AI compute engine, is vulnerable to a critical remote code execution flaw (CVE-2025-62593, CWE-94/CWE-352) in versions prior to 2.52.0, caused by an insufficient guard against browser-based attacks: the software distinguishes browser traffic only by checking that the User-Agent header starts with 'Mozilla', but the fetch specification allows that header to be modified. An attacker can combine DNS rebinding with a crafted User-Agent so that a developer's Firefox or Safari browser silently sends malicious requests to locally running Ray services after the developer visits an attacker-controlled website or is served a malicious advertisement (malvertising). Successful exploitation yields full remote code execution on the machine running Ray, with high confidentiality, integrity and availability impact reflected in the CVSS 4.0 score of 9.4. Affected users are developers running Ray as a development tool on any version before 2.52.0, which is the fixed release. The flaw is being actively exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-17, a public proof of concept is available in the project's GitHub security advisory (GHSA-q279-jhrf-cc6v), and EPSS estimates a 16.9% probability of exploitation in the next 30 days.

Do: Upgrade Ray to version 2.52.0 or later immediately, in line with CISA KEV and BOD 26-04 patching requirements. Until patched, avoid browsing untrusted websites (including ad-serving pages) while Ray development services are running, and restrict network access to locally running Ray services. Focus triage on machines where developers use Firefox or Safari alongside Ray, and hunt for signs of compromise since the flaw is actively exploited.

Improper Authentication in ownCloud Server Allows Unauthenticated File Access

ownCloud Server versions from 10.6.0 up to (but not including) 10.13.1 accept WebDAV pre-signed URLs even when no signing key is configured for the file owner, an improper authentication flaw (CWE-287). A remote attacker who knows a victim's username can therefore access, modify, or delete that user's files without any credentials, with no privileges or user interaction required (CVSS 9.8). Any organization running a self-hosted ownCloud Server instance in the affected version range is exposed, especially internet-facing deployments. CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2026-08-27, confirming exploitation in the wild, and EPSS assigns a 43.2% probability of exploitation within 30 days (99th percentile). No public proof-of-concept code is known, but recent press reports of attacks against ownCloud (including theft of records at a Philippine research body) indicate active targeting of ownCloud flaws.

Do: Upgrade to ownCloud Server 10.13.1 or later immediately, prioritizing internet-facing instances, as the flaw is on CISA's KEV list with BOD 26-04 patching deadlines. Until patched, configure signing keys for users where possible and restrict internet exposure of the pre-signed URL/WebDAV endpoints, and review server logs for unauthenticated file access, modification, or deletion tied to known usernames.

Unauthenticated .NET Deserialization RCE in Ajax.NET Professional (ajaxpro.2)

Ajax.NET Professional (distributed as the ajaxpro.2 package) is vulnerable to insecure deserialization (CWE-502): it deserializes arbitrary .NET classes supplied by the client without validating which types may be instantiated. Because AjaxPro exposes HTTP endpoints for browser-to-server AJAX calls, a remote, unauthenticated attacker can send a crafted serialized payload to any reachable AjaxPro endpoint and abuse .NET deserialization gadget chains to execute code on the server. Successful exploitation yields full remote code execution with high impact on confidentiality, integrity, and availability (CVSS 3.1 score of 9.8, network vector, no privileges or user interaction required). Any application running any version of ajaxpro.2 / Ajax.NET Professional is affected; the provided data specifies no fixed version, so defenders must rely on vendor guidance for patched releases. The flaw was added to CISA's Known Exploited Vulnerabilities catalog on 2026-08-26, carries an EPSS 30-day exploitation probability of 83.6%, has public PoC code available, and Talos Intelligence reporting links it to the Chinese-speaking threat actor UAT-10147, which deploys the SPECTRE malware with an EDR bypass and a Linux rootkit in post-compromise operations.

Do: Inventory your ASP.NET estate for AjaxPro usage (web.config references, AjaxPro HTTP handlers) and prioritize any internet-facing instance for remediation. Upgrade ajaxpro.2 to the latest vendor release per vendor instructions — the provided data specifies no fixed version — or, if patching is not immediately possible, restrict or block access to AjaxPro endpoints from the internet. Because the flaw is on CISA's KEV under BOD 26-04, apply mitigations within the required timeline and hunt exposed servers for post-compromise tooling, as Talos reports UAT-10147 deploying SPECTRE with an EDR bypass and a Linux rootkit.
