OpenClaw before 2026.8.1 Session Cancellation Authorization Bypass
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
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.
