Summary
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.
