Cisco searched for IOS XR bugs and found so many it rolled them into an update release
Cisco patched three critical flaws, including CVE-2026-20212 unauthenticated remote root code execution in Nexus 9000 switches; no exploitation observed yet.
Cisco disclosed three critical-rated flaws found during a comprehensive internal security review. CVE-2026-20274 and CVE-2026-20279, both CVSS 9.8, affect the IOS XR carrier-grade operating system and are fixed in newly released versions. CVE-2026-20212 lets unauthenticated remote attackers execute code with root privileges on some Nexus 9000 Series Switches by reaching TCP ports 43210 and 43211 in the default Layer 3 VRF; no software fix exists yet, only infrastructure ACL mitigations. Cisco says it has not observed attacks against these flaws.

GitLab CVSS 10 File-Read Flaw Draws In-the-Wild Probes After Disclosure
GitLab patched CVE-2026-85706, a CVSS 10.0 unauthenticated path traversal enabling arbitrary file reads, already probed in the wild.
GitLab released patches for a maximum-severity path traversal flaw (CVE-2026-85706, CVSS 10.0) in the repository commits API, caused by improper path confinement and missing authentication enforcement, allowing unauthenticated arbitrary file reads. watchTowr observed active in-the-wild probes starting 06:00 UTC on September 11, 2026; exploitation requires at least one public project and enables theft of credentials, secrets, and configuration data. GitLab also patched CVE-2026-87719 (CVSS 9.9), an insecure deserialization bug in Enterprise Edition allowing authenticated Duo Chat users to access Advanced Search configurations and sensitive credentials via crafted GraphQL subscription arguments. Affected versions include 18.7 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2, and the flaw follows the recently exploited GraphQL code injection bug CVE-2026-19478.

SAP Patches Critical Extended Passport Processing Vulnerability
SAP patches CVSS 10.0 flaw CVE-2026-44756 (OVERPASS) enabling unauthenticated RCE in S/4HANA and NetWeaver, plus three other criticals; no in-the-wild exploitation reported.
CVE-2026-44756 is a CVSS 10.0 memory corruption flaw in Extended Passport (EPP) deserialization, triggered when a user session opens across web, SAP GUI, and RFC vectors.

September 2026 Patch Tuesday: Record patch count, 2 zero-days, and a SigRed successor
Microsoft's September 2026 Patch Tuesday delivers a record patch count, fixing two exploited zero-days and a wormable DNS flaw dubbed a SigRed successor.
Microsoft's September 2026 Patch Tuesday sets another record patch count, fixing two vulnerabilities exploited as zero-days: CVE-2026-81963, a Windows Update Stack low-privilege-to-SYSTEM escalation reported by MSTIC, and CVE-2026-85880, a Windows Advanced Local Procedure Call escalation reported by Proofpoint. Zero Day Initiative's Dustin Childs urges priority on a cluster of 20 potentially wormable bugs including DNS RCE CVE-2026-69730, described as a spiritual successor to SigRed, plus Kerberos authentication bypass CVE-2026-69676 that could give any authenticated domain user RCE on domain controllers, and Exchange RCE CVE-2026-55007 via a malicious Visio attachment. All Windows fixes are bundled in cumulative updates, and experts stress prioritizing exploitable, reachable flaws over raw patch counts.

Critical Keycloak Password Reset Flaw Could Let Unauthenticated Attackers Take Over Any Account
Red Hat patched critical Keycloak flaw CVE-2026-18963 (CVSS 9.1) allowing unauthenticated attackers to take over any account, including administrative ones.
Keycloak and Red Hat patched CVE-2026-18963, a CVSS 9.1 flaw (CWE-640) caused by improper state validation in the reset-credentials flow, letting an unauthenticated remote attacker force a password reset without the emailed action token and achieve full account takeover, including admin accounts. Upstream Keycloak 26.7.2 and Red Hat Build of Keycloak 26.4.15/26.6.6 contain fixes; four RHSA errata were issued August 18, 2026. No evidence of exploitation or public exploits exists as of August 24, 2026; mitigation is disabling the Forgot Password feature in all realms.

ZDI-26-538: (Pwn2Own) Microsoft Exchange Improper Authorization Privilege Escalation Vulnerability
ZDI discloses a Pwn2Own Microsoft Exchange privilege-escalation flaw (CVE-2026-62911, CVSS 8.8) where the required authentication can be bypassed.
ZDI advisory ZDI-26-538 describes CVE-2026-62911, an improper authorization vulnerability in Microsoft Exchange rated CVSS 8.8. Remote attackers can escalate privileges, and while authentication is nominally required, the existing authentication mechanism can be bypassed. The vulnerability was demonstrated at Pwn2Own.

September 2026 Microsoft Patch Tuesday, (Tue, Sep 8th)
Microsoft's September 2026 Patch Tuesday fixes a record 973 vulnerabilities, including 113 critical and two Windows privilege-escalation flaws already exploited in the wild.
Microsoft patched 973 vulnerabilities this month, its largest Patch Tuesday ever and far above the previous record of 664 set in July 2026, with 113 rated critical. Two Important elevation-of-privilege flaws (CVSS 7.8) are confirmed exploited in the wild: CVE-2026-81963 in the Windows Update Stack (improper link resolution, affects Windows 11 and Server 2025) and CVE-2026-85880 in Windows ALPC (heap-based buffer overflow allowing sandbox escape to SYSTEM, affects Windows 10 and Server 2012-2022). Critical unauthenticated RCEs (CVSS 9.8) were also fixed in Skype for Business Server (CVE-2026-66302), Windows Message Queuing (CVE-2026-69579), and Windows RRAS (CVE-2026-69590). SANS urges prioritizing the two exploited EoP fixes, then patching exposed MSMQ, RRAS, and Skype for Business deployments.

Revolut Data Breach Via Fake Government Requests – What We Know So Far
Revolut confirmed attackers extracted customer KYC records by sending fraudulent data requests from a spoofed or compromised government agency email domain.
Revolut confirmed a data breach in which an unauthorized party obtained sensitive customer records by submitting fraudulent information requests from an email account on a legitimate government agency domain with valid SPF/DKIM/DMARC authentication. Disclosed data could include full names, dates of birth, passport or driving-license copies, onboarding facial images, IBANs, account statements, withdrawal records, and complete transaction histories including Bitcoin activity. Crypto investigator ZachXBT assessed the operation targeted high-net-worth users, while a threat actor using the name 'IAmNotAVillain' claimed Italian law-enforcement departments were compromised over six months with 147 GB of material, claims that remain unverified. Revolut says only a limited number of customers were affected, blocked the email address, and notified regulators and affected customers, stating its systems and funds were not compromised.

CISA Adds Two Known Exploited Vulnerabilities to Catalog
CISA added two actively exploited MikroTik RouterOS vulnerabilities, CVE-2026-67277 and CVE-2026-86060, to its KEV catalog, mandating federal remediation.
CISA added CVE-2026-67277 (missing authentication for a critical function) and CVE-2026-86060 (improper neutralization of argument delimiters in a command), both in MikroTik RouterOS, to the Known Exploited Vulnerabilities Catalog based on evidence of active exploitation. Under BOD 26-04, Federal Civilian Executive Branch agencies must prioritize rapid remediation of these flaws on publicly exposed assets that grant total control post-exploitation. Agencies are also required to check whether systems were compromised before patches were applied.

PaperCut Zero-Day Under Active Attack: Emergency Patch Released
PaperCut warns that a zero-day in NG and MF print management products is being actively exploited, shipping emergency patches with no CVE assigned yet.
PaperCut Software confirmed active exploitation of a zero-day affecting PaperCut NG and MF, with confirmed customer incidents, and released emergency patches on Friday ahead of technical details or a CVE assignment. The company urges customers to restrict web access to trusted IP addresses, disconnect application servers from the internet, and watch for indicators including tampered or truncated server.log files, database error strings, and suspicious activity involving pc-app.exe. The article recalls the May 2023 exploitation of CVE-2023-27350 and CVE-2023-27351 by the financially motivated Lace Tempest group, a Clop ransomware RaaS affiliate, though no attacker attribution has been given for the current campaign.
