Advisory
Source description from Wordfence Intelligence, credited to Julio Potier.
The iThemes Security plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the wp_ajax_itsec_file_change_warning_ajax function in versions up to, and including, 5.3.5. This makes it possible for authenticated attackers to perform administrative actions.
