WordPress Plugin Vulnerabilities

Restore PayPal Standard for WooCommerce <= 3.1.0 - Payment Bypass via PDT Underpayment

Description

The plugin does not validate the amount actually paid against the order total in its PayPal Data Transfer return handler, allowing a customer to pay less than the order total and still have the order marked as fully paid when the PayPal Data Transfer feature is enabled.
