Description
The MasterStudy LMS Pro plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in the install_and_activate_plugin function in all versions up to, and including, 4.7.9.

The vulnerability is difficult to exploit due to timing requirements and environmental factors.
