WordPress 的 PDF Invoices & Packing Slips for WooCommerce 插件在所有版本（包括 5.16.1 及更早版本）中均存在存储型跨站脚本（Stored XSS）漏洞，原因是输入清理和输出转义不足。该漏洞允许未经身份验证的攻击者在页面中注入任意 Web 脚本，当用户访问被注入的页面时，这些脚本将被执行。由于 WooCommerce 的 和 函数不会移除不包含字面量 字符的实体编码字符串，恶意载荷在初始存储阶段得以保留，从而使未经身份验证的访客结账订单能够植入恶意内容。

Vulnerability Title
PDF Invoices & Packing Slips for WooCommerce <= 5.16.1 - Unauthenticated Stored Cross-Site Scripting via Billing First Name / Last Name / Company Fields
Source: CVE Program / CVE List V5
Vulnerability Description
The PDF Invoices & Packing Slips for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Billing First Name / Last Name / Company Fields in all versions up to, and including, 5.16.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload survives initial storage because WooCommerce's sanitize_text_field() and wc_clean() do not strip entity-encoded strings containing no literal '<' character, allowing unauthenticated guest-checkout orders to plant the malicious content.
