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.
