🔓 Security researchers warn that attackers are exploiting the critical CVE-2025-11953 flaw in the React Native Metro server to drop malicious Windows and Linux payloads. The issue abuses the development-only /open-url HTTP endpoint, which accepts POST requests and can pass a user-supplied URL unsanitized to the system open() call. JFrog disclosed the bug and it was fixed in @react-native-community/cli-server-api v20.0.0+, but active exploitation (Metro4Shell) has been observed delivering base64 PowerShell stagers and UPX-packed binaries.

🔎 The Russia-linked threat actor APT28 has been observed exploiting CVE-2026-21509 in targeted Microsoft Office document attacks as part of Operation Neusploit. Zscaler ThreatLabz reported activity beginning on January 29, 2026, using localized lures and server-side geofilters to deliver malicious DLLs only to intended victims in Ukraine, Slovakia, and Romania. The exploit chains employ RTF/Word files that drop two distinct loaders: a C++ email stealer named MiniDoor and a more elaborate PixyNetLoader, which uses steganography and COM hijacking to deploy a Covenant Grunt implant. The campaign demonstrates focused espionage objectives, targeted evasion, and persistent C2 capabilities.

🔒 A high-severity vulnerability (CVE-2026-25253, CVSS 8.8) in OpenClaw allowed a crafted link or webpage to exfiltrate a stored gateway token and enable one-click remote code execution.

⚠️Two critical sandbox escape vulnerabilities in n8n allow authenticated users to achieve remote code execution on affected instances. JFrog researchers reported that flaws in the JavaScript expression engine and the Python Code node can bypass sandboxing protections, exposing workflow engines to host-level compromise. The JavaScript issue stems from a missed edge case in AST-based sanitization when expressions are passed to a Function constructor; the Python escape affects Internal execution mode. Both flaws carry high severity and have been patched—organizations should update to the specified releases and restrict who can create or edit workflows until upgrades are applied.

⚠️ CISA warns of a critical Missing Authentication for Critical Function vulnerability (CVE-2026-1453) in KiloView Encoder Series devices that could let an unauthenticated attacker create or delete administrator accounts and gain full administrative control. Multiple E1, E1-s, E2, G1, P1, P2 and RE1 hardware and firmware builds are affected. No public exploitation has been reported to CISA, and KiloView has not engaged with CISA; users should minimize network exposure, ensure devices are not directly reachable from the Internet, and contact KiloView support for guidance.

⚠️ SolarWinds has released updates for Web Help Desk to address multiple high‑severity vulnerabilities, including four critical flaws that can enable authentication bypass and remote code execution. Affected issues include deserialization and hard‑coded credential bugs tracked as CVE‑2025‑40536 through CVE‑2025‑40554. Rapid7 highlights that the deserialization flaws are particularly exploitable without authentication. SolarWinds fixed the issues in WHD 2026.1 and customers are urged to upgrade immediately.

⚠️ SolarWinds has issued emergency updates for Web Help Desk (WHD) to patch six vulnerabilities—four rated critical—that include unauthenticated data deserialization RCEs and authentication bypasses.
