Mitigation checklist
- Do not set spec.routeHostName to values outside the operator's own namespace service names. Restrict which users can create or modify Hawtio custom resources via RBAC. Audit existing Hawtio CR instances for unexpected routeHostName values and rotate any TLS certificates that may have been issued with incorrect Common Names.
