Quick assessment

Affected
Unknown Shared Files
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.

Shared Files WordPress 插件在 1.7.67 之前版本，以及 shared-files-pro WordPress 插件在 1.7.70 之前版本，其文件上传处理程序未执行权限（capability）检查。该处理程序针对未认证用户注册，仅通过一个在非认证用户可访问的页面上输出的 nonce 进行保护。因此，未认证访客可以将文件上传到一个公开可访问的目录中，并可以从响应中读取服务器的绝对路径。上传的文件类型受限于 WordPress 允许的 MIME 类型，因此无法上传可执行的 PHP 文件。

Vulnerability Title
Shared Files < 1.7.70 - Unauthenticated Limited File Upload
Source: CVE Program / CVE List V5
Vulnerability Description
The Shared Files WordPress plugin before 1.7.67, shared-files-pro WordPress plugin before 1.7.70 do not perform a capability check in their file-upload handler, which is registered for unauthenticated users and protected only by a nonce that is output on public pages, so an unauthenticated visitor can upload files to a publicly accessible directory and read the server's absolute path from the response. Uploads are limited to WordPress's allowed MIME types, so executable PHP cannot be uploaded.
