以下是对该漏洞描述的中文翻译： Shared Files WordPress 插件在 1.7.67 之前，以及 shared-files-pro WordPress 插件在 1.7.68 之前，未能正确净化（sanitize）从前端文件提交中获取的文件路径，且其单遍路径遍历过滤器可以被绕过。这使得未认证用户能够存储一个指向 uploads 目录之外的路径。当对应的文件条目随后被永久删除时，服务器上的任意文件（例如 wp-config.php）会被删除，从而导致服务中断（DoS）并可能导致站点被接管。

Vulnerability Title
Shared Files < 1.7.68 - Unauthenticated Arbitrary File Deletion via Path Traversal
Source: CVE Program / CVE List V5
Vulnerability Description
The Shared Files WordPress plugin before 1.7.67, shared-files-pro WordPress plugin before 1.7.68 do not properly sanitize a file path taken from a frontend file submission and their single-pass traversal filter is bypassable, allowing unauthenticated users to store a path that points outside the uploads directory. When the corresponding file entry is later permanently deleted, an arbitrary file on the server (such as wp-config.php) is deleted, leading to denial of service and potential site takeover.
