The Ad Inserter – Ad Manager & AdSense Ads plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.8.18 via the ai_wp_footer_hook. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract sensitive data including the server's internal IP address, PHP configuration, WordPress and theme versions, hardening constants, the plugin's full block matrix, and all post meta values including underscore-prefixed protected keys such as API tokens and private integration state written by other plugins.
