Unknown User Frontend

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 4.3.14 版本之前的 User Frontend WordPress 插件中，部分由用户提供的值在反映到公开可访问的 AJAX 响应中的 HTML 属性之前，未经过清理和转义处理，从而导致反射型跨站脚本（XSS）漏洞。受影响的接口由一个仅对未登录请求有效的匿名 nonce（一次性令牌）进行访问控制，因此攻击载荷仅针对未登录访客执行，不会影响已认证用户。

Vulnerability Title

WP User Frontend < 4.3.14 - Reflected XSS via 'field_attr' Parameter

Source: CVE Program / CVE List V5

Vulnerability Description

The User Frontend WordPress plugin before 4.3.14 does not sanitise and escape some user-supplied values before reflecting them into HTML attributes in a publicly reachable AJAX response, leading to Reflected Cross-Site Scripting. The affected action is gated by an anonymous nonce that only validates for logged-out requests, so the payload executes against logged-out visitors rather than authenticated users.
