Brave Popup Builder <= 0.8.7 - Unauthenticated Arbitrary Shortcode Execution
The Brave Popup Builder plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 0.8.7. This is due to passing a user-controlled URL parameter through do_shortcode() before output in a hidden form field without authentication. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes registered on the site by supplying a crafted UTM parameter that pre-fills a hidden form field.
