Description
Brave CMS is an open-source CMS. Prior to commit 6c56603, page and article body content entered through the CKEditor rich-text editor is stored verbatim in the database and subsequently rendered with Laravel Blade's unescaped output directive {!! !!}. Any JavaScript or HTML injected by an editor-role user is permanently stored and executed in every visitor's browser upon page load. This issue has been patched via commit 6c56603.
