Description
The Popup Builder, Forms, CRM & Email Marketing Automation plugin for WordPress is vulnerable to SQL Injection via the 'show_pages_list', 'not_show_pages_list', 'show_categories_list' and 'not_show_categories_list' parameters when saving a popup in all versions up to, and including, 2.0.0. This is due to the submitted IDs being concatenated directly into INSERT queries without sanitization or integer casting. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL to existing queries and extract sensitive information from the database.
