Technical details
The vulnerability is a session fixation issue in the password change functionality. When a user changes their password via edit_user_core() or admin_edit_user_core(), the new password is stored in the database but existing authenticated sessions are not revoked. An attacker in possession of a valid session token (via theft, interception, or prior compromise) can continue using that token to maintain authenticated access until the session expires naturally. The fix explicitly calls _invalidate_user_sessions(user.id) after password updates to ensure all existing sessions are terminated. This is a network-accessible vulnerability affecting authenticated users or attackers with valid session tokens.
