Smart Popup by Supsystic < 2.0.2 - Admin+ SQLi via Popup Page/Category Binding

The Customer Engagement System WordPress plugin before 2.0.2 does not safely build the SQL statements that store a popup's page and category visibility rules, concatenating request-supplied ID values directly into an INSERT statement with no parameter binding or integer cast, allowing an authenticated administrator to inject arbitrary SQL and read the contents of the WordPress database.
