| Doc Text: |
A flaw was found in Kubernetes. This flaw allows an actor that controls the responses of the MutatingWebhookConfiguration or the ValidatingWebhookConfiguration requests to redirect kube-apiserver requests to the private network 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, potentially revealing sensitive information in its responses.
