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 \u0027none\u0027 algorithm, you have to explicitly specify that in `jwt.verify()` options."

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\".
