CVE-2026-16947

Total Processing Card Payments for WooCommerce <= 7.3 - Unauthenticated SSRF leading to Payment Bypass and Gateway Credential Disclosure

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.
