    {

      "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\u2019t need to allow for the `none` algorithm. If you need 'none' algorithm, you have to explicitly specify that in `jwt.verify()` options.\n"

      "value": "En las versiones `&lt;=8.5.1` de la librer\u00eda `jsonwebtoken`, la falta de definici\u00f3n del algoritmo en la funci\u00f3n `jwt.verify()` puede provocar que se omita la validaci\u00f3n de firmas debido a que se utiliza de manera predeterminada el algoritmo `none` para la verificaci\u00f3n de firmas. Los usuarios se ven afectados si no especifica algoritmos en la funci\u00f3n `jwt.verify()`. Este problema se ha solucionado; actualice a la versi\u00f3n 9.0.0, que elimina la compatibilidad predeterminada con el algoritmo none en el m\u00e9todo `jwt.verify()`. No habr\u00e1 ning\u00fan impacto si actualiza a la versi\u00f3n 9.0.0 y no necesita permitir el algoritmo \"none\". Si necesita el algoritmo 'none', debe especificarlo expl\u00edcitamente en las opciones `jwt.verify()`."
