Upstream source description

The Ninja Forms WordPress plugin 3.15.3 does not escape submitted form field values before outputting them on the submission edit screen in the admin area, which could allow unauthenticated users to submit values through a public form that then execute in the browser of any high-privileged user who reviews the submission.
