WP Fast Total Search < 1.81.282 - Unauthenticated SQL Injection

Description

The WP Fast Total Search – The Power of Indexed Search plugin for WordPress is vulnerable to generic SQL Injection via the 'form_data[s]' parameter in all versions up to, and including, 1.80.280 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.
