Summary

The Kali Forms — Contact Form & Drag-and-Drop Builder WordPress plugin before 2.4.13 does not sanitise a form field's caption before outputting it as a column header on the administrator form-entries screen, allowing users with Contributor-level access or above to store JavaScript that executes in an administrator's session. A missing capability check in the Kali Forms — Contact Form & Drag-and-Drop Builder WordPress plugin before 2.4.13's post-duplication action additionally lets the Contributor publish the malicious form so an administrator renders it.
