What the vulnerability does
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.
Explanation of Vulnerability in Simple Terms
Ad Inserter versions 2.8.16 and earlier lack proper authorization checks, allowing unauthenticated attackers to read sensitive information. The vulnerability requires only network access and no user interaction. Site administrators should update to a version newer than 2.8.16 to prevent unauthorized data disclosure.
What an attacker can do
Read sensitive data without logging in.
Potential impact on your site
Attackers can access confidential information exposed by the plugin without needing an account.
Conditions required to exploit
Network access only; no authentication or user interaction required.
