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

Published Aug 10, 2026 · Updated Aug 11, 2026 · Assigned by WPScan

Description

The Accept PayPal & Stripe with Subscriptions for WooCommerce WordPress plugin through 3.1.0 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.
