OpenClaw versions 2026.4.7 before 2026.4.14 contain a privilege escalation vulnerability where heartbeat owner downgrade logic skips webhook wake events carrying untrusted content. Attackers can exploit this by sending untrusted webhook wake events to preserve owner-like execution context when the run should have been downgraded.
