Statmatic is a Laravel and Git powered content management system (CMS). Prior to 6.6.2, stored XSS in the control panel color mode preference allows authenticated users with control panel access to inject malicious JavaScript that executes when a higher-privileged user impersonates their account. This has been fixed in 6.6.2.
