Description
Taipy configures its socket.io server with wildcard CORS origin and credential flag enabled, allowing any web page to establish credentialed WebSocket connections to victim applications. Attackers can open socket.io sessions from arbitrary domains and invoke state variable modifications and action callbacks without CSRF protection.
