Attackers can host a page titled KitchenOwl at a URL matching /recipe/<id>. The follow-up requests.get() call can then be redirected or DNS-rebound to loopback, private-network, or cloud-metadata addresses, exposing internal services.","summary":"KitchenOwl's recipe import fetches a second URL without the IP filter applied to the first request, so a crafted page can redirect or DNS-rebind the server to loopback, private-network or cloud-metadata addresses.
