Upstream source description

The MW WP Form WordPress plugin before 5.1.6 does not sanitise and escape some of its form settings before outputting them back in an admin dashboard page, which could allow users with a role as low as Editor to perform Stored Cross-Site Scripting attacks against high privilege users such as admin.
