The Auth0 Next.js SDK is a library for implementing user authentication in Next.js applications. Versions starting from 4.0.1 and prior to 4.5.1, do not invoke .setExpirationTime when generating a JWE token for the session. As a result, the JWE does not contain an internal expiration claim. While the session cookie may expire or be cleared, the JWE remains valid. This issue has been patched in version 4.5.1.
According to WASC, “Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization.”
