What is CVE-2026-17016?
A critical vulnerability has been discovered in the 'Accept PayPal & Stripe with Subscriptions' plugin for WooCommerce (up to version 3.1.0). As the plugin does not validate the actual paid amount against the order total in its PayPal Data Transfer handler, an attacker can pay less than the order total and still have the order marked as fully paid. Immediate update to the latest patched version is strongly recommended.
