      "value": "El gestor de guardado de /settings de changedetection.io construye un diccionario de actualización a partir de form.data[’application’] y lo fusiona ciegamente en la configuración de aplicación almacenada a través de .update(). Debido a que WTForms representa una casilla de verificación desmarcada como False en lugar de ’unchanged’, y solo el campo ’password’ se trata de forma especial para este problema, una solicitud POST a /settings que omite el campo api_access_token_enabled (por ejemplo, una solicitud programada mínima) deshabilita silenciosamente la aplicación de claves API para toda la API REST, exponiendo la lista completa de seguimiento, el historial y la configuración a solicitudes no autenticadas."
