CVE-2026-123528

Vikunja before 2.7.1 contains an insufficient session expiration vulnerability that allows holders of revoked access tokens to keep authenticating because SetupTokenMiddleware skips session and account-status checks. Attackers with a stolen token can, after logout, password reset, or account disabling, mint OAuth sessions via /oauth/authorize or tk_ API tokens for persistent access.
