The Cost Calculator Builder plugin for WordPress is vulnerable to time-based SQL Injection via the ‘orderids’ parameter in all versions up to, and including, 3.2.67 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Cost Calculator Builder PRO plugin for WordPress is vulnerable to blind time-based SQL Injection via the ‘data’ parameter in all versions up to, and including, 3.2.15 due to insufficient escaping on the user supplied 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.

The Cost Calculator Builder WordPress plugin before 3.2.43 does not have CSRF checks in some AJAX actions, which could allow attackers to make logged in users perform unwanted actions via CSRF attacks.

Cost Calculator Builder Pro plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to 3.1.72, via the senddemowebhook() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
