Summary

OpenClaw: Read-scoped identity-bearing HTTP clients could kill sessions via /sessions/:sessionKey/kill

Details

Summary

Before OpenClaw 2026.4.2, POST /sessions/:sessionKey/kill did not enforce write scopes in identity-bearing HTTP modes. A caller limited to read-only operator scopes could still terminate a running subagent session.

Impact

A read-scoped caller could perform a write-class control-plane mutation and interrupt delegated work. This was an authorization bug on the HTTP scope boundary, not a shared-secret compatibility exception.

Affected Packages / Versions

Affected versions: <= 2026.4.1

OpenClaw < 2026.4.2 - Authorization Bypass in Session Termination Endpoint

Summary

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.
