No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

OpenClaw before 2026.5.26 contains an authorization bypass vulnerability where a surviving pairing-scoped device session can re-establish node token authority after revocation. Attackers with a paired device can regain WebSocket node-level access without renewed approval, weakening revocation controls and maintaining unauthorized access longer than intended.
