Mitigation checklist

Recommended fix / mitigation

Apply NetworkPolicy egress restrictions to the openshift-console namespace to limit the console pod's outbound connectivity to required endpoints only (Kubernetes API server, OAuth server, monitoring). Note that a blanket default-deny egress policy will break console functionality. Monitor console access logs for unusual POST requests to /api/dev-console/webhooks/ paths with non-standard hostName values pointing to internal addresses or containing query separators.
