Description

Overview

Auth0 NextJS v4.0.1 to v4.5.0 does 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.

Am I Affected?

You are affected if you are using Auth0 NextJS SDK v4.

Fix

Upgrade to v4.5.1.
