## Description

The Parsi Date plugin for WordPress is vulnerable to payment bypass via the Mellat, Melli, Parsian, and Pasargad WooCommerce payment gateway callbacks in all versions up to, and including, 6.4. This is due to insufficient verification that the bank token, sale reference, invoice number, and amount sent to the public callback belong to the order named by the order_id parameter, and to missing protection against reused receipts. This makes it possible for unauthenticated attackers to mark orders as paid by using a valid receipt from a different, cheaper order. Exploitation requires one of the affected gateways to be enabled in WooCommerce.
