Quads Ads Manager for Google AdSense 3.0.4 - Authenticated (Subscriber+) Payment Bypass to Unpaid Ad Placement Acquisition
The Quads Ads Manager for Google AdSense plugin for WordPress is vulnerable to Payment Bypass in all versions up to 3.0.4. This is due to missing server-side payment verification with the configured payment gateway before marking an order as paid. This makes it possible for authenticated attackers, with subscriber-level access and above, to obtain a paid ad placement without completing payment by triggering the order completion flow without a verified gateway transaction.
