📛 CVE Title
Vikunja before 2.7.1 Insufficient Session Expiration via HTTP Token Middleware
Description
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.
