What is CVE-2026-17016?

The Accept PayPal & Stripe with Subscriptions for WooCommerce plugin for WordPress fails to properly validate the payment amount against the total order value during the PayPal Data Transfer return process. This oversight permits customers to complete transactions by paying an amount less than the order total, while the system erroneously recognizes the order as fully paid. This vulnerability could lead to financial discrepancies and undermine business integrity if exploited.
