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.
