// If `ENABLE_HCM_INTERNAL_NETWORKS` is set to true, MeshNetworks can be used to
// to explicitly define the networks in Envoy's internal address configuration.
// Envoy uses the IPs in the `internalAddressConfig` to decide whether or not to sanitize
// Envoy headers. If the IP address is listed an internal, the Envoy headers are not
// sanitized. As of Envoy 1.33, the default value for `internalAddressConfig` is set to
// an empty set. Previously, the default value was the set of all private IPs. Setting
// the `internalAddressConfig` to all private IPs (via Envoy's previous default behavior
// or via the MeshNetworks) will leave users with an Istio Ingress Gateway potentially
// vulnerable to `x-envoy` header manipulation by external sources. More information about
// this vulnerability can be found here:
// https://github.com/envoyproxy/envoy/security/advisories/GHSA-ffhv-fvxq-r6mf
// To preserve headers, you must explicitly configure MeshNetworks and set
// `ENABLE_HCM_INTERNAL_NETWORKS` to true. Envoy's `internalAddressConfig` will be set to
// the endpointed specified by `fromCidr`.
