CVE-2026-25253 (CVSS 8.8) enables millisecond-speed one-click RCE against OpenClaw. The attack exploits missing WebSocket origin header validation: visiting a malicious page triggers cross-site WebSocket hijacking → exfiltrates gateway token → disables sandboxing → escapes Docker → full RCE on host. Endor Labs separately disclosed 6 additional vulnerabilities (SSRF, path traversal, auth bypass). 1,862 publicly exposed instances detected. Patched in v2026.1.29 with Trust-on-First-Use and origin validation. Users must rotate gateway tokens and API keys immediately. (The Hacker News, Endor Labs)
