phpMyAdmin through 5.2.3 contains an sql injection vulnerability in Designer saveSetting() that allows authenticated users to inject SQL via unescaped json_encode() output. Attackers can send crafted index or value parameters with operation=save_setting_value to /database/designer to overwrite other users' designer settings or run controluser subqueries.
