CVE-2025-46344: AUTH0 Nextjs-AUTH0

Medium severity, CVSS 4.9. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• AUTH0 Nextjs-AUTH0: from 4.0.1, before 4.5.1 (fixed in 4.5.1)
