CVE-2026-107321— W3 Total Cache < 2.10.6 - Author+ Path Traversal via CDN Media Library Import

Quick assessment

Affected
Unknown W3 Total Cache
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.

W3 Total Cache WordPress 插件在版本 2.10.6 之前存在安全漏洞。该漏洞未将媒体导入文件复制到文档根目录的限制，也未对其实施有效的文件类型限制。因此，具备作者（Author）或更高权限的用户可以植入恶意内容。一旦管理员执行导入操作，任意可通过服务器读取的文件将被复制到公开的 Web 服务目录中，导致未授权用户能够访问并获取这些文件。

Vulnerability Title
W3 Total Cache < 2.10.6 - Author+ Path Traversal via CDN Media Library Import
Source: CVE Program / CVE List V5
Vulnerability Description
The W3 Total Cache WordPress plugin before 2.10.6 does not confine a media-import file copy to the document root, nor enforce an effective file-type restriction on it, allowing users with the Author role or higher to plant content that, once an administrator runs the import, copies an arbitrary server-readable file into a publicly served directory, exposing it to unauthenticated retrieval.
