OpenClaw < 2026.4.2 - Authorization Bypass in Session Termination Endpoint
OpenClaw before 2026.4.2 fails to enforce write scopes on the POST /sessions/:sessionKey/kill endpoint in identity-bearing HTTP modes. Read-scoped callers can terminate running subagent sessions by sending requests to this endpoint, bypassing authorization controls.
