WP Fast Total Search exposes an unauthenticated SQL injection
WP Fast Total Search through 1.80.280 registers the wpfts_autocomplete AJAX action for logged-out visitors. wpfts_autocomplete_proc() copies attacker-controlled form_data[s] into a WP_Query, after which the plugin's SQL-building path incorporates search terms into queries without full parameterization. An unauthenticated attacker can alter those queries and extract sensitive database information. The CNA record does not identify the exact records obtainable. Version 1.81.282 replaces the vulnerable string construction with placeholders and $wpdb->prepare().

Technical 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.
