Complianz Premium 6.3.3-6.3.5 is vulnerable to Auth. SQL Injection (SQLi) vulnerability

The Complianz plugin for WordPress is vulnerable to SQL Injection via unescaped translations in versions up to, and including, 6.3.3 (Free) and 6.3.5 (Premium) due to insufficient escaping on the user supplied translation (either from a translation file or a user with translator role through a translation plugin) and lack of sufficient preparation on the existing SQL query. This makes it possible for attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
