⚠️ CISA has added a high-severity flaw in Gogs to its Known Exploited Vulnerabilities list after active attacks were observed. Tracked as CVE-2025-8110 (CVSS v4.0 8.7), the issue stems from improper handling of symbolic links in the PutContents API and allows authenticated users to overwrite files outside repositories, potentially enabling remote code execution. Wiz reported hundreds of compromises and Censys shows over 1,600 exposed instances; no official patch is yet available, so administrators should apply immediate mitigations such as disabling open registration and restricting access.

🔒 Three widely used open-source AI/ML Python libraries — NVIDIA NeMo, Salesforce uni2TS, and Apple ml-flextok — were found vulnerable to remote code execution when model metadata was treated as executable configuration. The root cause is unsafe use of configuration-driven instantiation (for example Hydra's instantiate()) that accepts attacker-controlled _target_ values. Vendors released patches and CVE notices; users should apply fixes, restrict allowed targets, and avoid loading models from untrusted sources.

⚠️ CISA has added CVE-2025-8110 to its Known Exploited Vulnerabilities catalog after reports of active exploitation targeting Gogs. The high-severity (CVSS 8.7) flaw is a path traversal in the repository file editor's PutContents API that mishandles symbolic links and can lead to remote code execution. There is not yet an official upstream patch, though GitHub pull requests show fixes have been merged and maintainers say new images will include the correction once built. Until patched, users should disable default open-registration, restrict server access behind VPNs or allow-lists, and apply other access controls; FCEB agencies must implement mitigations by Feb 2, 2026.

⚠️ The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has ordered federal agencies to patch a high-severity remote code execution flaw in Gogs tracked as CVE-2025-8110. The issue is a path traversal weakness in the PutContents API that lets authenticated attackers overwrite files outside repositories via symbolic links, enabling arbitrary command execution. Patches released last week add symlink-aware path validation; agencies must remediate by February 2, 2026. Administrators are advised to disable default open registration and restrict server access.

⚠️ A maximum-severity flaw dubbed Ni8mare (CVE-2026-21858) affects n8n and can allow unauthenticated remote attackers to take control of local instances by exploiting improper input validation in Form Submission triggers. Researchers say the bug enables secret exfiltration, session forgery, file injection, and command execution. Administrators should upgrade to n8n 1.121.0 immediately or restrict public webhook/form endpoints as a temporary mitigation.

🔐 This week's recap highlights how small oversights and automation conveniences have become widespread attack vectors, enabling rapid, large-scale compromise. Key incidents include a maximum-severity RCE in n8n (Ni8mare, CVE-2026-21858) affecting self-hosted instances, the 2M-device Kimwolf Android botnet, and malicious Chrome extensions that exfiltrated AI conversations. The report catalogs numerous trending CVEs and active campaigns, emphasizing that familiar tools and exposed services are the biggest risks today.

🛡️ Trend Micro has released a security update for Apex Central after vulnerability management vendor Tenable identified multiple serious flaws affecting all on-premises builds earlier than 7190. The most severe is a 9.8-rated LoadLibraryEX issue that can allow an unauthenticated attacker to force the server to load and execute an attacker-controlled DLL as SYSTEM. Two additional high-severity, unauthenticated flaws can cause denial-of-service. Trend Micro urges customers to apply build 7190 and review remote access controls immediately.

🔍 Huntress says Chinese-speaking threat actors used a compromised SonicWall VPN appliance in December 2025 to deploy a multi-stage exploit against VMware ESXi, leveraging three zero-day vulnerabilities disclosed by Broadcom in March 2025 (CVE-2025-22224/22225/22226). The toolkit includes an orchestrator dubbed MAESTRO, an unsigned kernel driver loaded via KDU, and a VSOCK-based ELF backdoor called VSOCKpuppet. The attack chain enabled VM-to-hypervisor escapes, remote control of ESXi hosts over VSOCK port 10000, and file transfer capabilities from guest VMs, all of which were halted by Huntress before a suspected ransomware stage could complete.

⚠️ Security researchers at Cyera disclosed a critical vulnerability dubbed Ni8mare in the workflow automation platform n8n, enabling remote code execution and potential full environment compromise. The flaw, tracked as CVE-2026-21858, carries a CVSS score of 10.0 and impacts roughly 100,000 servers. The root cause is a Content-Type confusion in webhook processing that lets attackers overwrite internal variables, read arbitrary files and inject malicious payloads. n8n released a patched build (1.121.0); administrators should upgrade immediately and rotate any exposed credentials and tokens.

⚠️ CISA has added a max-severity remote code execution flaw in HPE OneView (CVE-2025-37164) to its Known Exploited Vulnerabilities catalog after HPE published an advisory and a patch.
