How to fix?
github.com/istio/istio/pilot/pkg/model to version 1.9.5, 1.8.6 or higher.
Affected versions of this package are vulnerable to Access Restriction Bypass. When a gateway is using the
AUTO_PASSTHROUGH routing configuration, attackers can bypass authorization checks and access unexpected services in the cluster.
This vulnerability only impacts usage of the
AUTO_PASSTHROUGH Gateway type, which is typically only used in multi-network multi-cluster deployments. See the Istio advisory for more information on triaging the impact of this vulnerability.
