Quick assessment

Affected
Unknown Advanced File Manager
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.

Advanced File Manager WordPress 插件在 5.4.13 版本之前，在其多个文件管理相关的 AJAX 操作中未执行权限校验。这使得任何被管理员授予了文件管理器访问权限的用户（最低权限角色为订阅者 Subscriber）都可以读取服务器上的任意文件——包括敏感的配置文件——以及覆盖现有的非 PHP 文件。攻击者可利用此漏洞窃取管理员账户凭据，进而完全控制整个网站。

Vulnerability Title
Advanced File Manager < 5.4.13 - Authenticated Arbitrary File Read and Write via fma_load_fma_ui
Source: CVE Program / CVE List V5
Vulnerability Description
The Advanced File Manager WordPress plugin before 5.4.13 does not perform capability checks in several of its file management AJAX actions, allowing users with any role to which an administrator has granted file-manager access (as low as Subscriber) to read arbitrary files on the server — including sensitive configuration files — and to overwrite existing non-PHP files, which can be leveraged to compromise administrator accounts and the whole site.
