Summary

The NEX-Forms WordPress plugin before 9.2.3 does not sanitise and escape some submitted form data before storing it and outputting it back in the admin dashboard, leading to a Stored Cross-Site Scripting vulnerability which could allow unauthenticated users to perform Stored Cross-Site Scripting attacks against high privilege users such as administrators when they view the submitted entries.
