Quick assessment

Affected
Unknown Cache Enabler
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.

Cache Enabler WordPress 插件在 1.8.17 版本之前，未对用于构建文件系统路径的 URL 进行验证，且未将由此产生的删除操作限制在缓存目录内。这使得未经身份验证的用户能够删除站点上的任意文件和目录，前提是该站点安装了另一个 1.8.17 版本之前的 Cache Enabler WordPress 插件，或者该插件将源自请求的 URL 传递给了其公开的缓存清除钩子（hook）。
