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. Attackers can send unauthenticated loopback HTTP and WebSocket requests to Canvas routes to bypass authentication and gain unauthorized access.
