Quick assessment

Affected
kiboit PhastPress
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.

WordPress 的 PhastPress 插件存在服务端请求伪造（Server-Side Request Forgery, SSRF）漏洞，影响所有 3.10 及以下版本。该漏洞源于插件的 /scripts 服务端点在构建其 URL 白名单时，动态地从攻击者可控制的 HTTP 'Host' 头中获取数据。这使得未经身份验证的攻击者能够通过伪造 Host 头以匹配任何目标 URL，从而绕过白名单限制，并强制服务器向任意内部或外部目标发起 HTTP 请求，进而返回响应内容。

Vulnerability Title
PhastPress <= 3.10 - Unauthenticated Server-Side Request Forgery via 'src' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The PhastPress plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 3.10 This is due to the scripts service endpoint constructing its URL whitelist dynamically from the attacker-controlled HTTP 'Host' header. This makes it possible for unauthenticated attackers to spoof the header to match any target URL, bypassing the whitelist and forcing the server to make HTTP requests to arbitrary internal or external destinations and return the response content.
