Summary
wger versions before 2.6 keep bearer-style API credentials valid after a user logs out or changes their password. A remote attacker who steals a victim's DRF authtoken or JWT refresh token can keep calling protected /api/v2/ endpoints until the token is rotated, deleted or expires. The flaw is insufficient session expiration (CWE-613).

Description from the CNA
wger is a free, open-source workout and fitness manager. Versions prior to 2.6 have a vulnerability in the authentication/session lifecycle of `wger` where bearer-style API credentials remain valid after a user logs out and after a user changes their password. An attacker who steals a victim’s DRF authtoken (`Authorization: Token ...`) or JWT refresh token can continue to access protected `/api/v2/*` endpoints until the token is manually rotated/deleted (DRF token) or naturally expires (JWT refresh). Version 2.6 contains a patch.
