Описание

A security issue was discovered in kube-apiserver that could allow node updates to bypass a Validating Admission Webhook. Clusters are only affected by this vulnerability if they run a Validating Admission Webhook for Nodes that denies admission based at least partially on the old state of the Node object. Validating Admission Webhook does not observe some previous fields.

A vulnerability was found in Kubernetes' kube-apiserver that could allow Node updates to bypass a Validating Admission Webhook. An authenticated user could exploit this by modifying Node properties to values that should have been prevented by registered admission webhooks.
