CVE-2025-4643

Lack of JWT Expiration after Log Out in PayloadCMS

Payload uses JSON Web Tokens (JWT) for authentication. After log out JWT is not invalidated, which allows an attacker who has stolen or intercepted token to freely reuse it until expiration date (which is by default set to 2 hours, but can be changed). This issue has been fixed in version 3.44.0 of Payload.
