      "value": "In versions `<=8.5.1` of `jsonwebtoken` library, lack of algorithm definition in the `jwt.verify()` function can lead to signature validation bypass due to defaulting to the `none` algorithm for signature verification. Users are affected if you do not specify algorithms in the `jwt.verify()` function. This issue has been fixed, please update to version 9.0.0 which removes the default support for the none algorithm in the `jwt.verify()` method. There will be no impact, if you update to version 9.0.0 and you don’t need to allow for the `none` algorithm. If you need 'none' algorithm, you have to explicitly specify that in `jwt.verify()` options."

Los usuarios se ven afectados si no especifica algoritmos en la función `jwt.verify()`. Este problema se ha solucionado; actualice a la versión 9.0.0, que elimina la compatibilidad predeterminada con el algoritmo none en el método `jwt.verify()`. No habrá ningún impacto si actualiza a la versión 9.0.0 y no necesita permitir el algoritmo \"none\". Si necesita el algoritmo 'none', debe especificarlo explícitamente en las opciones `jwt.verify()`."
