CVE-2019-1002100 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 10.52% chance of exploitation in the next 30 days.
