Quick assessment

Affected
archetyped Favicon Rotator
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 插件“Favicon Rotator”存在反射型跨站脚本漏洞（Reflected Cross-Site Scripting）。在 1.2.11 及更早的所有版本中，由于对以“fvrt_”为前缀的请求参数缺乏足够的输入清理和输出转义，攻击者可以将任意 Web 脚本注入到页面中。若攻击者能成功诱导用户执行某些操作（例如点击恶意链接），则这些脚本将在用户的浏览器中执行。由于该漏洞无需身份认证，任何未认证的远程攻击者均可利用此漏洞。
