## Affected

- Unknown Ninja Forms: from 3.15.3, fixed in 3.15.4

## 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.

## What to do

- Check your stack: if you ship or depend on Unknown Ninja Forms, upgrade to a fixed version (3.15.4) per the references below.
