Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Empty --token= and --http-host= values disabled authentication and widened the bind to 0.0.0.0, allowing any network client to access the MCP server without credentials.
Authentication Bypass / Unauthorized Access: The POST /sse endpoint was reachable from LAN and cross-origin without a bearer token, allowing unauthenticated remote control of the browser automation bridge.
Unauthenticated Control Channel Hijack: The WebSocket control channel bound to all interfaces without authentication, enabling LAN and cross-origin web pages to hijack the extension socket.
