Technical description

The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.50 does not properly sanitise and restrict HTML in user-submitted content before storing it and rendering it to other users, allowing users with subscriber-level accounts and above to perform stored HTML injection, such as embedding iframes, that can be leveraged for phishing and content spoofing against other users viewing the content.
