Technical details

The Web UI and REST interfaces do not properly invalidate active user sessions after security-sensitive account changes including password changes, password resets, or role and privilege updates (CWE-613: Insufficient Session Expiration). An authenticated user with a stolen or intercepted session token can reuse it to access the account without re-authentication. The vulnerability requires network access and prior authentication but can lead to account impersonation and privilege reuse.
