The NEX-Forms WordPress plugin before 8.4.4 does not escape its form name, which could lead to Stored Cross-Site Scripting issues. By default only SuperAdmins (in multisite) / admins (in single site) can create forms, however there is a settings allowing them to give lower roles access to such feature.
