The vulnerability is due to node-jose following the JSON Web Signature (JWS) standard for JSON Web Tokens (JWTs). This standard specifies that a JSON Web Key (JWK) representing a public key can be embedded within the header of a JWS. This public key is then trusted for verification. An attacker could exploit this by forging valid JWS objects by removing the original signature, adding a new public key to the header, and then signing the object using the (attacker-owned) private key associated with the public key embedded in that JWS header."}, {"lang": "es", "value": "Una vulnerabilidad en la librer\u00eda de c\u00f3digo libre node-jose de Cisco en versiones anteriores a la 0.11.0 podr\u00eda permitir que un atacante remoto no autenticado vuelva a firmar los tokens empleando una clave que est\u00e1 embebida en el token. Esta vulnerabilidad se debe a que node-jose sigue el est\u00e1ndar JSON Web Signature (JWS) para JWT (JSON Web Tokens).
