WooCommerce 插件“Total”在处理银行卡支付时（版本 7.3 及更早版本）存在安全漏洞：该插件在未充分验证用户提供的路径前，便使用其构建服务器端验证请求，同时未校验响应的真实性。这使得未经身份验证的攻击者能够将验证请求重定向到任意主机（从而泄露商户的支付网关凭证），并伪造成功响应，将任意 WooCommerce 订单标记为“已支付”。

Vulnerability Title
Total Processing Card Payments for WooCommerce <= 7.3 - Unauthenticated SSRF leading to Payment Bypass and Gateway Credential Disclosure
Source: CVE Program / CVE List V5
Vulnerability Description
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.
