# CVE-2026-16947

> 9.1 CRITICAL

## Beschreibung

The Total processing card payments for WooCommerce WordPress plugin through 7.3 does not validate a user-supplied path before using it to build a server-side verification request, and does not verify the authenticity of the response, allowing unauthenticated attackers to redirect that request to an arbitrary host (disclosing the merchant's payment-gateway credentials) and to forge a success response that marks arbitrary WooCommerce orders as paid.
