Summary Duplicate Advisory: OpenClaw: Gateway Canvas local-direct requests bypass Canvas HTTP and WebSocket authentication ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-6mqc-jqh6-x8fc. This link is maintained to preserve external references. ### Original Description OpenClaw before 2026.3.23 contains an authentication bypass vulnerability in the Canvas gateway where authorizeCanvasRequest() unconditionally allows local-direct requests without validating bearer tokens or canvas capabilities.
