Detailed vulnerability description
The vulnerability allows a remote user to reach network destinations that should have been blocked by OpenClaw policy.
The vulnerability exists due to improper access control in browser CDP discovery when handling blocked WebSocket URLs. A remote user can provide a blocked WebSocket URL through a lower-trust caller or configured input path to reach network destinations that should have been blocked by OpenClaw policy.
Only instances where the affected feature is enabled and reachable are vulnerable, and practical impact depends on whether lower-trust input can reach that path.
