Advisory

Source description from Wordfence Intelligence, credited to Donato Di Pasquale, Francesco Marano.

The Build App Online plugin for WordPress is vulnerable to SQL Injection via an AJAX action available to unprivileged users in versions up to, and including, 1.0.18 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.
