CVE-2026-41347Network attack vector

Unauthorized operator actions via unchecked browser origins

Published Apr 23, 2026 · Updated Apr 23, 2026

CSRF in OpenClaw before 2026.3.31 allows remote attackers to perform unauthorized HTTP operator actions through a victim's browser. Gateway trusted-proxy HTTP authorization accepted identity-bearing requests without comparing the Origin header against allowed origins. Exploitation requires a trusted-proxy deployment and a browser that sends a cross-origin request with the proxy-authenticated user's identity.
