CVE-2026-17016

Name of the Vulnerable Software and Affected Versions Accept PayPal & Stripe with Subscriptions for WooCommerce WordPress plugin versions prior to 3.1.1

Description The plugin fails to validate the actual amount paid against the order total within its PayPal Data Transfer return handler. This flaw allows a customer to pay an amount lower than the order total, yet the system still marks the order as fully paid, provided the PayPal Data Transfer feature is enabled.

Recommendations Update the plugin to version 3.1.1 or later. As a temporary mitigation, disable the PayPal Data Transfer feature.
