What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

OpenClaw versions before 2026.8.1 contain an authorization bypass vulnerability in webhook TaskFlow cancellation that allows attackers to cancel unrelated sessions. An attacker with a webhook route secret can supply an arbitrary child session key to cancel ACP or subagent work outside the route's configured authority.
