CVE-2026-35634
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.
Does this matter?
Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.
