CWE-441

Description

A flaw was found in hawtio-operator. The operator holds routes/custom-host:create permission cluster-wide and writes the tenant-supplied spec.routeHostName value from the Hawtio custom resource directly into the Route spec without validation or authorization checks. A namespace edit user, who normally cannot set custom Route hostnames, can use the operator as a confused deputy to claim arbitrary externally-routable hostnames, enabling subdomain takeover and, in combination with the auto-grant OAuthClient, OAuth redirect hijack.
