This includes internal IP addresses, PHP configuration, WordPress and theme versions, plugin data, and protected keys such as API tokens. The vulnerability arises via the ai_wp_footer_hook and exposes sensitive information to unauthorized actors.

The Ad Inserter – Ad Manager & AdSense Ads WordPress plugin up to version 2.8.18 is vulnerable to reflected cross-site scripting (XSS) via the 's' search parameter. This vulnerability arises from insufficient input sanitization and output escaping.

An attacker can inject arbitrary scripts that execute when a user clicks a crafted link. The vulnerability has a medium severity with a CVSS score of 6.1.

The Ad Inserter – Ad Manager & AdSense Ads WordPress plugin up to version 2.8.18 is vulnerable to reflected cross-site scripting (XSS) via the Referer header. This occurs when an ad block uses the '{search-query}' dynamic tag, which processes the HTTP Referer header insufficiently, allowing injection of arbitrary JavaScript. Exploitation requires an ad block configured with this tag and automatic insertion enabled. The vulnerability can lead to script execution in the context of any site visitor, including administrators.

The Ad Inserter – Ad Manager & AdSense Ads plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 2.8.16 via the 'data' attribute of the [adinserter] shortcode. This is due to the replace_ai_tags() function processing a {reusable-block-N} tag pattern that calls get_post_field('post_content', N) without verifying the requesting user's capability with current_user_can('read_post'), without restricting the post type to 'wp_block', and without checking the post status. This makes it possible for authenticated attackers, with Contributor-level access and above, to read the full content of arbitrary posts including Private, Draft, Pending, Trashed, and password-protected posts owned by other users, by placing the shortcode in a post they own and previewing it.
