      "value": "python-jwt is a module for generating and verifying JSON Web Tokens. Versions prior to 3.3.4 are subject to Authentication Bypass by Spoofing, resulting in identity spoofing, session hijacking or authentication bypass. An attacker who obtains a JWT can arbitrarily forge its contents without knowing the secret key. Depending on the application, this may for example enable the attacker to spoof other user\u0027s identities, hijack their sessions, or bypass authentication. Users should upgrade to version 3.3.4. There are no known workarounds."

Un atacante que obtiene un JWT puede falsificar arbitrariamente su contenido sin conocer la clave secreta. Dependiendo de la aplicaci\u00f3n, esto puede permitir al atacante, por ejemplo, falsificar la identidad de otros usuarios, secuestrar sus sesiones o omitir la autenticaci\u00f3n. Los usuarios deben actualizar a versi\u00f3n 3.3.4. No se presentan mitigaciones conocidas."
