Technical details

The vulnerability exists in User::verifyCode() in objects/user.php due to PHP loose comparison of the recoverPass token. An authenticated attacker can craft a verification code with an arbitrary users_id and recoverPass flag set to true, exploiting the predictable salt-based token validation. This allows account takeover of any user's email verification status without authentication.

Timeline
