Istio is an open platform to connect, manage, and secure microservices. In versions on the 1.15.x branch prior to 1.15.3, a user can impersonate any workload identity within the service mesh if they have localhost access to the Istiod control plane. Version 1.15.3 contains a patch for this issue. There are no known workarounds.
