Affected packages

• Go istio.io/istio: >= 1.1.0, < 1.1.7 → fixed in 1.1.7

Description

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.
