Microsoft’s Patching

Microsoft's September Patch Tuesday fixes a record 972 vulnerabilities, 112 rated critical, amid AI-accelerated vulnerability discovery.

Microsoft's September 2026 Patch Tuesday patches a record ~972 vulnerabilities, 112 rated critical, following records of 570 two months ago and ~620 last month. Schneier attributes the surge to AI-powered vulnerability finding, citing an open letter from OpenAI, Anthropic, AWS, Google, Microsoft and roughly 100 organizations warning of an AI-enabled attack tsunami. He predicts AIs will reverse-engineer exploits from patches, weaponizing flaws immediately upon release and shrinking the patch window to 'immediately.'

ICS Patch Tuesday: Schneider Electric, Siemens Fix Critical Flaws

September ICS Patch Tuesday brings critical fixes from Schneider Electric, Siemens, and Aveva, including CVSS 9.2 authentication flaw CVE-2026-3869 in Modicon M580 controllers.

Schneider Electric's September advisories include a critical authentication vulnerability, CVE-2026-3869 with a CVSS score of 9.2, in Modicon M580 and Modicon M580 Safety controllers, plus high-severity bugs in PowerLogic T300 and EcoStruxure IT Data Center Expert. Siemens published nine new advisories, four rated critical across Reyrolle 7SR5, Open Interface Services, Industrial Edge Management, and SIMOVE Fleetmanager and SIPLANT, and began rolling out fixes for CVE-2026-31431, a 7.8-rated Linux kernel flaw enabling root shell access. Aveva disclosed four flaws in Pipeline Integrity Monitor's PIMBoards, including a hardcoded encryption key and MD5-hashed passwords, plus an unsafe deserialization issue in Enterprise SCADA. Rockwell Automation separately issued nine advisories covering RSLinx Classic and multiple controller products.

China-Made ZBT Routers Ship With Two Implants Giving Unauthenticated Attackers Root Access

VulnCheck discloses two factory implants, SPEAKINGSTONE and DARKLANTERN, in ZBT router firmware granting unauthenticated remote attackers root command execution.

VulnCheck found two previously undocumented implants in firmware from Shenzhen Zhibotong Electronics (ZBT), tracked as CVE-2026-74232 (SPEAKINGSTONE) and CVE-2026-74233 (DARKLANTERN), each rated 9.8 on CVSS 3.1. SPEAKINGSTONE (yunmgrd) beacons to a hardcoded C2 over UDP port 10000 and supports root command execution, PPPoE credential exfiltration, DNS hijacking, and reverse SSH tunnels; DARKLANTERN (infosrvd) listens on UDP port 9992 with weak hardcoded authentication. Scanning found 203 internet-facing DARKLANTERN instances across 22 countries, and 392 devices reported to the SPEAKINGSTONE backup C2, nearly all in China on China Mobile. No fixed firmware release is named, and ZBT's white-labeling means model number rather than brand is the reliable detection check.

KindaRails2Shell threatens Ruby on Rails apps (CVE-2026-66066)

Critical CVE-2026-66066 in Rails' Active Storage/libvips allows unauthenticated arbitrary file read and possible RCE; active exploitation now observed.

CVE-2026-66066 (KindaRails2Shell), discovered by Ethiack researchers and independently by RyotaK of GMO Flatt Security, lets attackers upload crafted files that exploit libvips' handling of specialty formats to read arbitrary files, including process environment secrets, potentially escalating to RCE. Default Rails 7.0+ setups using Active Storage with the vips processor are affected before versions 7.2.3.2, 8.0.5.1, and 8.1.3.1; fixes shipped July 29, 2026, with VIPS_BLOCK_UNTRUSTED as a partial mitigation. Proof-of-concept exploits circulated after disclosure, and VulnCheck updated that it observed active exploitation originating from a single French IP establishing C2 to a host in Israel. Akamai deployed WAF rules, but experts stress patching and credential rotation over filtering alone.

GitLab Patches Critical Unauthenticated GraphQL Vulnerability

GitLab issued an emergency patch for a critical unauthenticated GraphQL flaw (CVE-2026-19478, CVSS 9.4) enabling remote modification or deletion of public projects.

GitLab patched CVE-2026-19478 (CVSS 9.4), an unauthenticated GraphQL directive flaw allowing remote modification or deletion of public projects and user data on self-managed servers. The emergency patch released August 17 covers versions 19.2.4, 19.1.6, 19.0.8, and 18.11.11, but no fixes exist for the 18.2-18.10 branches. A second issue, a CSRF weakness in GraphQL multiplex queries (CVE-2026-19650, CVSS 7.1), shipped in the same release. No exploitation or public PoC has been observed; the flaw was reported by hiimguardian through HackerOne.

Emerging Threat: (CVE-2026-60004) Gitea Remote Code Execution via ...

CVE-2026-60004 (CVSS 9.8) lets attackers with repository write access achieve RCE on self-hosted Gitea servers via malicious git hooks; fixed in 1.27.1.

CVE-2026-60004 is a CWE-94 code injection flaw in Gitea's POST /api/v1/repos/{owner}/{repo}/diffpatch endpoint, disclosed July 28, 2026 with a CVSS v3.1 score of 9.8 and credited to researcher Shai Rod (NightRang3r). An add/add collision with the three-way merge fallback (--3, Git 2.32+) writes attacker-controlled content into the temporary bare clone's hooks directory, where it executes as a live Git hook running commands as the Gitea OS user. Exploitation requires repository write access, but Gitea's default open registration allows anonymous users to obtain it, exposing app.ini secrets, database credentials, OAuth tokens, and mounted repositories; a public PoC requires no outbound callback. All releases from 1.17 through 1.27.0 are affected; the fix shipped in Gitea 1.27.1 on July 27, 2026, and Gitea Cloud instances were upgraded automatically.

GeoNetwork Fixes Unauthenticated RCE Chain Affecting Government Geoportal Backends

GeoNetwork patched two chained flaws (CVE-2026-63219, CVE-2026-58400) enabling unauthenticated RCE in government geospatial metadata catalogs.

Two flaws in the open-source GeoNetwork catalog chain into unauthenticated RCE: a missing authorization check on the formatter upload endpoint (CVE-2026-63219, CVSS 8.6) and an unsafe Saxon XSLT processor configuration allowing Java execution (CVE-2026-58400, CVSS 9.1). Fixes shipped in versions 4.4.12 and 4.2.17 on July 8, 2026, with details published August 31. Ethiack fingerprinted 121 internet-exposed vulnerable deployments across 39 countries, 89% tied to government or military agencies. No exploitation in the wild or KEV listing was reported at disclosure.
