High (7.1) in nadh listmonk. EPSS 0.3% chance of exploitation in the next 30 days. Fixed in github.com/knadh/listmonk 1.1.1-0.20260329113754-1b5e8d38c778.
listmonk is a standalone, self-hosted, newsletter and mailing list manager. From version 4.1.0 to before version 6.1.0, a session management vulnerability allows previously issued authenticated sessions to remain valid after sensitive account security changes, specifically password reset and password change. As a result, an attacker who has already obtained a valid session cookie can retain access to the account even after the victim changes or resets their password. This weakens account recovery and session security guarantees. This issue has been patched in version 6.1.0.
