Summary
The SEO Booster plugin for WordPress is vulnerable to time-based SQL Injection via the 'orderby' parameter in all versions up to, and including, 7.3.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Although esc_sql() and sanitize_text_field() are applied, neither neutralizes SQL keywords, commas, parentheses, or subquery syntax in an unquoted ORDER BY context, leaving the clause fully attacker-controlled.
