FluentCart <= 1.6.4 - Unauthenticated Unauthorized Customer Account Access
The FluentCart plugin for WordPress is vulnerable to Account Takeover in all versions up to, and including, 1.6.4. This is due to automatic linking of a customer record to a WordPress user account by matching the attacker-supplied billing email against get_user_by('email') during checkout, without verifying the requester controls that address. This makes it possible for unauthenticated attackers to obtain access to an existing customer account and its stored purchase history by supplying that customer's email address during a guest checkout.
