Upgrade k8s.io/apimachinery/pkg/util/proxy to version 0.19.0-rc.1 or higher.

Overview

k8s.io/apimachinery/pkg/util/proxy is a package that provides transport and upgrade support for proxies.

Affected versions of this package are vulnerable to Privilege Escalation. If an attacker is able to intercept certain requests to the Kubelet, they can send a redirect response that may be followed by a client using the credentials from the original request. This can lead to compromise of other nodes.
