Starting in version 4.16.0 and prior to version 6.6.0, Gradio applications running outside of Hugging Face Spaces automatically enable \"mocked\" OAuth routes when OAuth components (e.g. `gr.LoginButton`) are used. When a user visits `/login/huggingface`, the server retrieves its own Hugging Face access token via `huggingface_hub.get_token()` and stores it in the visitor's session cookie. If the application is network-accessible, any remote attacker can trigger this flow to steal the server owner's HF token. The session cookie is signed with a hardcoded secret derived from the string `\"-v4\"`, making the payload trivially decodable. Version 6.6.0 fixes the issue."},{"lang":"es","value":"Gradio es un paquete Python de código abierto diseñado para la creación rápida de prototipos. A partir de la versión 4.16.0 y antes de la versión 6.6.0, las aplicaciones de Gradio que se ejecutan fuera de Hugging Face Spaces habilitan automáticamente rutas OAuth 'simuladas' cuando se utilizan componentes OAuth (por ejemplo, 'gr.LoginButton'). Cuando un usuario visita '/login/huggingface', el servidor recupera su propio token de acceso de Hugging Face a través de 'huggingface_hub.get_token()' y lo almacena en la cookie de sesión del visitante. Si la aplicación es accesible por red, cualquier atacante remoto puede activar este flujo para robar el token HF del propietario del servidor. La cookie de sesión está firmada con un secreto codificado derivado de la cadena '-v4', lo que hace que la carga útil sea trivialmente decodificable.
