WordPress 的 Slim Jetpack 插件存在存储型跨站脚本（Stored XSS）漏洞，影响所有 2.7.0.1 及更早版本。该漏洞源于对参数 （即“网站联系字段”）的输入清理和输出转义不足。攻击者无需身份验证即可向页面注入任意 Web 脚本，当用户访问被注入的页面时，这些脚本便会执行。此外，表单提交时的 nonce 和身份验证检查仅对已登录用户生效，因此未登录访客可通过任何包含 短代码的页面存储攻击载荷。

Vulnerability Title
Slim Jetpack <= 2.7.0.1 - Unauthenticated Stored Cross-Site Scripting via Contact Form 'Website' Field
Source: CVE Program / CVE List V5
Vulnerability Description
The Slim Jetpack plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'g<PAGE_ID>-website (Website contact-field)' parameter in all versions up to, and including, 2.7.0.1 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 nonce and authentication checks on form submission are only enforced for logged-in users, allowing unauthenticated visitors to store payloads via any page containing the [contact-form] shortcode.
