Istio 1.1.x through 1.1.6 has Incorrect Access Control. When disablePolicyChecks is set to false, inbound TCP connections do not generate Check requests to istio-policy and external authorization is not applied.

This behavior is a result of a change to istio/pilot/pkg/networking/plugin/mixer/mixer.go in 1.1.
