## Affected

- Unknown WP Directory Kit: fixed in 1.5.7

## Description

The WP Directory Kit WordPress plugin before 1.5.7 does not perform any authorization check on one of its public AJAX actions and returns unfiltered database rows, allowing unauthenticated attackers to retrieve the usernames and email addresses of users holding the WP Directory Kit WordPress plugin before 1.5.7's own roles.

## What to do

- Check your stack: if you ship or depend on Unknown WP Directory Kit, upgrade to a fixed version (1.5.7) per the references below.
