What it is

The Ad Inserter – Ad Manager & AdSense Ads plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.8.16 due to a missing capability check in the `ai_ajax` function. This makes it possible for unauthenticated attackers to view the contents of ad blocks that an administrator has restricted to administrator-only visibility.
