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 Autoptimize 插件在所有版本（包括 3.1.15.1 及更早版本）中，由于输入清理和输出转义不足，存在通过 REQUEST_URI 路径触发存储型跨站脚本（Stored XSS）漏洞。这使得未经身份验证的攻击者能够向页面中注入任意 Web 脚本，当用户访问被注入的页面时，这些脚本将被执行。利用该漏洞的前提条件是：必须启用 Critical CSS 功能并配置有效的 API 密钥，因为这是触发未经身份验证的前端请求通过 函数创建队列条目的必要条件。

Vulnerability Title
Autoptimize <= 3.1.15.1 - Unauthenticated Stored Cross-Site Scripting via REQUEST_URI Path
Source: CVE Program / CVE List V5
Vulnerability Description
The Autoptimize plugin for WordPress is vulnerable to Stored Cross-Site Scripting via REQUEST_URI Path in all versions up to, and including, 3.1.15.1 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. Exploitation requires the Critical CSS feature to be active with a valid API key configured, as this is the precondition for unauthenticated frontend requests to trigger queue entries via ao_ccss_enqueue().
