Versions before and including `1.4.1` are vulnerable to reflected XSS. An attacker can execute arbitrary code by providing an XSS payload in the `error` query parameter which is then processed by the callback handler as an error message. You are affected by this vulnerability if you are using `@auth0/nextjs-auth0` version `1.4.1` or lower **unless** you are using custom error handling that does not return the error message in an HTML response. Upgrade to version `1.4.1` to resolve. The fix adds basic HTML escaping to the error message and it should not impact your users."},{"lang":"es","value":"El SDK de Auth0 Next.js es una biblioteca para implementar la autenticación de usuarios en las aplicaciones Next.js. Las versiones anteriores a la \"1.4.1\" e incluyéndola, son vulnerables a un ataque de tipo XSS reflejado. Un atacante puede ejecutar código arbitrario al proporcionar una carga útil de tipo XSS en el parámetro de consulta \"error\" que luego es procesado por el controlador de devolución de llamada como un mensaje de error. Está afectado por esta vulnerabilidad si está usando \"@auth0/nextjs-auth0\" versión \"1.4.1\" o inferior **a menos que** esté usando un manejo de errores personalizado que no devuelva el mensaje de error en una respuesta HTML. Actualizar a versión \"1.4.1\" para solucionarlo.
