The RapidLoad – Optimize Web Vitals Automatically plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to a missing capability check on the uucss_data, update_rapidload_settings, wp_ajax_update_htaccess_file, uucss_update_rule, upload_rules, get_all_rules, update_titan_settings, preload_page, and activate_module functions in all versions up to, and including, 2.4.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify plugin settings or conduct SQL injection attacks.
