The Ad Inserter – Ad Manager & AdSense Ads plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URL Parameters in iframe Mode in all versions up to, and including, 2.8.15 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploitation requires that iframe mode (AI OPTION IFRAME) is enabled on at least one ad block displayed on the targeted page, which is a non-default but supported configuration commonly used for AdSense and JavaScript-based ads.
