Overview
Affected versions of this package are vulnerable to Weak Password Recovery Mechanism for Forgotten Password via the ResetPassword function and the background token cleanup process. An attacker can gain persistent unauthorized access to user accounts by reusing intercepted password reset tokens, even after the victim changes their password.
Note: This is possible due to the failure to invalidate tokens upon use and a logic flaw in the cleanup process that leaves old tokens valid indefinitely.
