CVE-2019-11254
The Kubernetes API Server component in versions 1.1-1.14, and versions prior to 1.15.10, 1.16.7 and 1.17.3 allows an authorized user who sends malicious YAML payloads to cause the kube-apiserver to consume excessive CPU cycles while parsing YAML.
Does this matter?
Lower severity and a low EPSS score (3.16%). Track it; it rarely justifies an emergency change on its own.
