The Royal Elementor Addons plugin for WordPress is vulnerable to insufficient access control in the 'wpr_save_mega_menu_settings' AJAX action in versions up to, and including, 1.3.59. This allows any authenticated user, including those with subscriber-level permissions, to enable and modify Mega Menu settings for any menu item.
WordPress Royal Elementor add-ons versions 1.3.59 and below suffer from cross site request forgery, insufficient access control, cross site scripting vulnerabilities.
