The Ads Pro Plugin - Multi-Purpose WordPress Advertising Manager plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.89. This is due to missing or incorrect nonce validation on the bsaCreateAdTemplate function. This makes it possible for unauthenticated attackers to inject and execute arbitrary PHP code via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
