Quick assessment

Affected
Unknown MasterStudy LMS WordPress Plugin
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.

WordPress 插件 MasterStudy LMS 在 3.7.50 版本之前存在一个安全漏洞。该漏洞源于插件在构建模板路径时，未对其中的一个显示样式（display-style）设置进行充分验证。攻击者可以利用此缺陷，以贡献者（Contributor）及以上权限的用户身份，在服务器上包含并执行任意的本地 PHP 文件。 尽管之前有一个版本已修复了类似的路径问题，但该问题在后续版本中未被彻底修复，因此即便某些版本被早期安全公告标记为“已修复”，该漏洞在这些版本中依然存在。

Vulnerability Title
MasterStudy LMS 3.5.29 - < 3.7.50 - Contributor+ LFI via Elementor Courses Categories Widget
Source: CVE Program / CVE List V5
Vulnerability Description
The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.50 does not validate one of its display-style settings before using it to build a template path, allowing users with the Contributor role and above to include and execute arbitrary local PHP files on the server. An equivalent path was corrected in an earlier release and this one was not, so the issue persists in versions the earlier advisory reports as fixed.
