Popup builder with Gamification, Multi-Step Popups, Page-Level Targeting, and WooCommerce Triggers <= 2.1.3 - Unauthenticated SQL Injection via 'id'

The Popup builder with Gamification, Multi-Step Popups, Page-Level Targeting, and WooCommerce Triggers plugin for WordPress is vulnerable to SQL Injection in all versions up to, and including, 2.1.3. This is due to insufficient escaping on the 'id' parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
