WordPress 的 WP Crowdfunding 插件存在存储型跨站脚本（Stored XSS）漏洞，受影响版本为 2.2.1 及更早的所有版本。该漏洞是由于对输入参数 'first_name' 的净化不足以及对输出的转义处理不当所致。 这意味着，拥有订阅者级别或更高权限的已认证攻击者，可以在页面上注入任意的 Web 脚本，这些脚本将在用户访问相应页面时自动执行。当管理员通过 ?show_user_id= 参数查看任意用户资料时，攻击者预先存储的脚本载荷将在管理员的浏览器会话中渲染并执行，从而实现跨权限的脚本

Vulnerability Title
WP Crowdfunding <= 2.2.1 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'first_name' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The WP Crowdfunding plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'first_name' parameter in all versions up to, and including, 2.2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. An administrator viewing any user's profile via the ?show_user_id= parameter will render the attacker's stored payload in the admin's browser session, enabling cross-privilege script execution.
