Advisory
Source description from Wordfence Intelligence, credited to So Sakaguchi.
The SiteGround Security plugin for WordPress is vulnerable to blind SQL Injection via some if its filtering and paging parameters in versions up to, and including, 1.3.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for administrator-level attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
