## Affected

- Unknown Guest posting / Frontend Posting / Front Editor: fixed in 5.0.6

## Description

The Guest posting / Frontend Posting / Front Editor WordPress plugin before 5.0.6 allows passing a URL parameter to regenerate a .json file based on demo data that it initially creates. If an administrator modifies the demo form and enables admin notifications in the Guest posting / Frontend Posting / Front Editor WordPress plugin before 5.0.6's settings, it is possible for an unauthenticated attacker to export and download all of the form data/settings, including the administrator's email address.

## What to do

- Check your stack: if you ship or depend on Unknown Guest posting / Frontend Posting / Front Editor, upgrade to a fixed version (5.0.6) per the references below.
