Description
Brave CMS is an open-source CMS. Prior to 2.0.6, an unrestricted file upload vulnerability exists in the CKEditor upload functionality. It is found in app/Http/Controllers/Dashboard/CkEditorController.php within the ckupload method. The method fails to validate uploaded file types and relies entirely on user input.
