WordPress 的 Password Protected 插件在所有 2.8.4 及更早版本中，由于输入清理和输出转义不足，存在通过其捆绑的 Freemius SDK 购买完成处理器引发的存储型跨站脚本（Stored XSS）漏洞。一旦站点完成 Freemius 的注册确认（即管理员点击“允许并继续”后的正常状态），该处理器会在任何来自已认证用户的 wp-admin 请求中处理 请求参数，且无需任何权限检查、Nonce 验证或购买验证，随后将该参数存储为持久的全站管理通知。这使得拥有订阅者级别及以上权限的已认证

Vulnerability Title
Password Protected <= 2.8.4 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Freemius purchase_completed Handler
Source: CVE Program / CVE List V5
Vulnerability Description
The Password Protected plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the bundled Freemius SDK's purchase-completion handler in all versions up to, and including, 2.8.4 due to insufficient input sanitization and output escaping. Once the site's Freemius opt-in is complete (the normal state after an administrator clicks "Allow & Continue"), the handler processes the 'purchased_plan' request parameter on any wp-admin request from an authenticated user without any capability, nonce, or purchase validation, and stores it in a persistent, site-wide administrative notice. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts that execute automatically when an administrator views a standard admin page such as their Profile page.
