In all Kubernetes versions prior to v1.11.8, v1.12.6, and v1.13.4, users that are authorized to make patch requests to the Kubernetes API Server can send a specially crafted patch of type “json-patch” (e.g. kubectl patch --type json
or "Content-Type: application/json-patch+json"
) that consumes excessive resources while processing, causing a Denial of Service on the API Server.
