The Form Maker by 10Web – Mobile-Friendly Drag & Drop Contact Form Builder plugin for WordPress is vulnerable to blind SQL Injection via the 'inputs' parameter in all versions up to, and including, 1.15.48 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 nonce required to reach the vulnerable handler is emitted to every public page that renders a form, making it trivially obtainable by an unauthenticated attacker from page source.
