Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.4.2

Description In identity-bearing HTTP modes, the software fails to enforce write scopes on the 'POST /sessions/:sessionKey/kill' endpoint. This authorization flaw allows callers with read-only operator scopes to perform write-class control-plane mutations, enabling them to terminate running subagent sessions and interrupt delegated work by sending requests to the affected endpoint using the sessionKey variable.

Recommendations Update to version 2026.4.2 or later.
