Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.3.23

Description OpenClaw contains an authentication bypass in the Canvas gateway. The authorizeCanvasRequest() function unconditionally allows local-direct requests without validating bearer tokens or canvas capabilities. This allows attackers to send unauthenticated HTTP and WebSocket requests to Canvas routes, bypassing authentication and gaining unauthorized access.

Recommendations Update to version 2026.3.23 or later.
