Official description

Brave CMS is an open-source CMS. Prior to 2.0.6, this vulnerability is a missing authorization check found in the update role endpoint at routes/web.php. The POST route for /rights/update-role/{id} lacks the checkUserPermissions:assign-user-roles middleware. This allows any authenticated user to change account roles and promote themselves to Super Admin. This vulnerability is fixed in 2.0.6.
