How to fix?

Upgrade k8s.io/kubernetes/pkg/kubectl/cmd to version 1.26.0-alpha.3 or higher.

Overview

k8s.io/kubernetes/pkg/kubectl/cmd is a package that provides the functions used by the kubectl command line tool under k8s.io/kubernetes/cmd. The functions are kept in this package to better support unit testing. The main() method for kubectl is only an entry point and should contain no functionality.

Affected versions of this package are vulnerable to Improper Input Validation. Kubectl does not neutralize escape, meta, or control sequences contained in the raw data it outputs to a terminal. This includes but is not limited to the unstructured string fields in objects such as Event objects.
