Vulnerability Overview

The uListing plugin for WordPress is vulnerable to Unauthenticated Arbitrary Account Changes in versions up to, and including, 1.6.6. This is due to missing login checks on the stm_listing_profile_edit AJAX action. This makes it possible for unauthenticated attackers to edit any account on the blog, such as changing the admin account's email address.
