WordPress 的 WooCommerce 3D 产品配置器插件（所有版本直至包括 2.16.2）存在远程代码执行漏洞，该漏洞可通过 'xpv_image' 参数利用。此问题源于 wp_loaded 处理程序缺少身份验证和 nonce 验证检查，且在将 'xpv_image' POST 参数回显到启用了 PHP 执行的 Dompdf 渲染 HTML 模板之前，未对其进行任何清理。这使得未授权的攻击者能够在服务器上执行恶意代码。处理程序中唯一的 nonce 和身份验证检查被完全包含在一个注释块中，且未被替换，导致

Vulnerability Title
3D Product configurator for WooCommerce <= 2.16.2 - Unauthenticated Remote Code Execution via 'xpv_image' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The 3D Product configurator for WooCommerce plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.16.2 via the 'xpv_image' parameter parameter. This is due to missing authentication and nonce checks on the wp_loaded handler combined with no sanitization of the xpv_image POST parameter before it is echoed unescaped into a Dompdf-rendered HTML template with PHP execution enabled. This makes it possible for unauthenticated attackers to execute code on the server. The only nonce and authentication check in the handler is entirely enclosed in a block comment with no replacement, making the endpoint reachable via a single unauthenticated POST to any URL on the site.
