Workarounds
CNA: Restrict ClusterLogForwarder write access to trusted administrators only. Review existing ClusterRoleBindings and RoleBindings that grant clusterlogforwarders write permission. Apply NetworkPolicy egress restrictions to the collector namespace to prevent collector pods from reaching arbitrary external endpoints. Deploy admission controller policies (OPA/Gatekeeper/Kyverno) to deny CLF resources whose outputs point to non-allowlisted URLs. Monitor for ClusterLogForwarder resources with outputs pointing to external URLs, especially those using token.from: serviceAccount.
