Description
The Order Tracking plugin for WordPress is vulnerable to payment bypass in all versions up to, and including, 3.5.4 due to the PayPal IPN handler marking the order referenced in a PayPal-verified notification as paid without checking the payment status, amount, currency or receiving account. This makes it possible for unauthenticated attackers to mark orders as paid without paying the order's price on sites where order payments are enabled.
