  • Source referencewordfence.com
Upstream source description

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 on the `ai-debug-code` URL-parameter. This makes it possible for unauthenticated attackers to view administrator-configured header and footer code blocks that have been disabled from public display.
