Description
OpenClaw versions prior to 2026.3.2 contain an authentication bypass vulnerability in the /api/channels route classification due to canonicalization depth mismatch between auth-path classification and route-path canonicalization. Attackers can bypass plugin route authentication checks by submitting deeply encoded slash variants such as multi-encoded %2f to access protected /api/channels endpoints.
