How to fix?

There is no fixed version for k8s.io/kubernetes.

Overview

k8s.io/kubernetes is a Production-Grade Container Scheduling and Management.

Affected versions of this package are vulnerable to Open Redirect. An actor that controls the responses of MutatingWebhookConfiguration or ValidatingWebhookConfiguration requests is able to redirect kube-apiserver requests to private networks of the apiserver. If that user can view kube-apiserver logs when the log level is set to 10, they can view the redirected responses and headers in the logs.

This vulnerability requires the -v log level to be set to a minimum of 10 and --profiling to be enabled on the kube-apiserver to be exploitable.
