CVE-2026-82617: Apache OpenNLP: ReDoS / stack exhaustion in RegexNameFinderFactory built-in EMAIL and URL patterns

Apache OpenNLP CVE-2026-82617: built-in EMAIL and URL regex name-finder patterns enable regular expression denial-of-service and stack exhaustion in affected releases.

CVE-2026-82617 affects Apache OpenNLP opennlp-core 3.0.0-M1 before 3.0.0-M6 and opennlp-tools 2.0.0 before 2.5.12. The DEFAULT_REGEX_NAME_FINDER.EMAIL and DEFAULT_REGEX_NAME_FINDER.URL patterns in RegexNameFinderFactory contain ambiguous nested quantifiers. Applications using these built-in finders on attacker-controlled input can be forced into regular expression denial of service or stack exhaustion. Fixes shipped in opennlp-tools 2.5.12 and 3.0.0-M6.

Critical Flaw in NASA/JPL Open-Source Spacecraft Command Software Allowed Unauthenticated Command Execution

NASA/JPL's AIT-GUI web console (CVSS 9.4) lacked authentication and CSRF protection, letting anyone send unauthenticated commands to spacecraft instruments; fixed in 2.5.2.

Cycode researchers found that AIT-GUI, the browser console of NASA/JPL's open-source AMMOS Instrument Toolkit, ran an HTTP server with no authentication, no session checks, and no CSRF protection on state-changing endpoints, allowing arbitrary commands to spacecraft instruments. The issue combines four weaknesses: binding to 0.0.0.0 regardless of configured host, missing authentication, missing CSRF defense, and path traversal in the /seq and /script/run endpoints. Tracked as GHSA-p9r8-2q67-fp86 with CVSS 9.4, it is fixed in AIT-GUI 2.5.2. The findings came from AI-assisted code analysis confirmed with working proofs-of-concept, including a headless-browser CSRF demonstration.

We got admin access to Baseten's production GitHub in 25 minutes

Strix autonomous hacking agent extracted a working GitHub token with repo admin rights from Baseten's public Harbor image; Baseten rotated it next day.

Strix, an autonomous hacking agent, scanned *.baseten.co without credentials and found a public Harbor container registry project anonymously exposing the baseten/baseten-app image. A GitHub personal access token for basetenbot, embedded in Docker build history since March 2023, still worked in July 2026 and granted admin/push rights to basetenlabs/baseten, flux-cd, and homebrew-tap plus read/write on private customer repos. Baseten, valued at $13 billion, confirmed the issue as critical and rotated the token within a day.

Microsoft Releases Emergency Windows 11 Update Following Patch Tuesday Bugs

Microsoft issued emergency Windows 11 update KB5129195 to fix Patch Tuesday regressions and fully close the CVE-2026-62721 privilege escalation flaw.

Microsoft shipped out-of-band cumulative update KB5129195 for Windows 11 24H2 and 25H2 (builds 26100.9457 and 26200.9457) after the September 8 Patch Tuesday rollup, which addressed over 960 CVEs including two actively exploited flaws, broke Remote Desktop Services, Hyper-V Plan9 folder sharing, and USB audio. The emergency release also strengthens the incomplete fix for CVE-2026-62721, an elevation-of-privilege flaw in the Windows User-Mode Power Service that could let a local attacker gain SYSTEM privileges. Companion patches cover Windows 11 26H1, Windows 10, and Windows Server. Some USB Audio Class 1.0 and AMD Radeon graphics issues remain unresolved.

Windows 11 Security Update KB5124008 Breaks Always-On VPN Connections

Microsoft's September 2026 Windows 11 update KB5124008 breaks certificate-based Always On VPN on some enterprise clients, forcing admins to pause rollout.

Microsoft's September 8, 2026 cumulative update KB5124008 for Windows 11 24H2 (build 26100.9445) and 25H2 (build 26200.9445) breaks certificate-based Always On VPN tunnels on some enterprise clients, with connectivity restored after uninstalling the update and rebooting. The issue was first detailed on Microsoft Q&A on September 9 by an administrator using Intune-deployed VPN profiles with RRAS and NPS on Windows Server 2019. The same mandatory Patch Tuesday package fixes two actively exploited zero-days, CVE-2026-81963 in the Windows Update Stack and CVE-2026-85880 in Windows Advanced Local Procedure Call, so many teams are pausing only VPN cohorts rather than blocking the full rollout.

Remote Desktop Services Failures on Windows Servers Following September Update

September 2026 Patch Tuesday updates cause Windows Server 2019/2022/2025 RDS sessions to freeze, forcing administrators to roll back.

Cumulative updates KB5122876 (Windows Server 2019), KB5122882 (2022), and KB5122871 (2025) trigger Remote Desktop Services freezes hours after boot, with RDP connections hanging at 'Connecting…' and Event ID 20498 logged. Administrators trace the fault to an apparent deadlock in RDPSERVERBASE!WDLIB_Close during session teardown; only hard resets restore service and the issue recurs. The same September release patched roughly 973 vulnerabilities, including two actively exploited zero-days (CVE-2026-81963, CVE-2026-85880, both in CISA's KEV) and a critical RDS RCE, CVE-2026-69525 (CVSS 9.8). Workarounds include DISM-based removal of the update or an unofficial FeatureManagement registry key disabling the suspected audio-redirection code path; Microsoft has not yet confirmed the bug.

Nearly 1 in 10 Exposed LiteLLM Gateways Accepted the Example "sk-1234" Admin Key

Wiz found 294 of 3,074 internet-facing LiteLLM gateways accepted the documented default admin key sk-1234, exposing provider API keys and cloud IAM credentials.

Wiz Research's February Shodan scan found 3,074 LiteLLM gateways, 294 of which accepted the setup guide's sk-1234 admin key; 191 had no master key set and would accept any credential. The master key doubles as the authentication switch, and before 1.82.0-stable a gateway started without one granted every request full admin rights, exposing stored provider API keys, prompts, and MCP-connected tools. A documented pass-through endpoint lacks checks against private and cloud metadata addresses, letting an admin-key holder retrieve cloud IAM credentials, though no real-world abuse is reported. Related LiteLLM flaws include CVE-2026-59821 (disputed guardrail code execution), CVE-2026-59822 (CVSS 8.8, added to CISA KEV on September 2 and observed against Wiz honeypots), and CVE-2026-42271, used to install a cryptominer.

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.
