Statamic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.16 and 6.7.2, an authenticated Control Panel user with access to live preview could use a live preview token to access restricted content that the token was not intended for. This has been fixed in 5.73.16 and 6.7.2.
