Summary
The Hustle – Email Marketing, Lead Generation, Optins, Popups plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'hustle_module_converted' AJAX action in all versions up to, and including, 7.8.10.2. This makes it possible for unauthenticated attackers to forge conversion tracking events for any Hustle module, including draft modules that are never displayed to users, thereby manipulating marketing analytics and conversion statistics.
