HIGH7.5EPSS 84.5%XML Entity Expansion and Improper Input Validation in Kubernetes API server in k8s.io/kubernetes
發布日:2021/5/18修改日:2026/4/28
也稱為:DEBIAN-CVE-2019-11253
描述
Improper input validation in the Kubernetes API server in versions v1.0-1.12 and versions prior to v1.13.12, v1.14.8, v1.15.5, and v1.16.2 allows authorized users to send malicious YAML or JSON payloads, causing the API server to consume excessive CPU or memory, potentially crashing and becoming unavailable. Prior to v1.14.0, default RBAC policy authorized anonymous users to submit requests that could trigger this vulnerability. Clusters upgraded from a version prior to v1.14.0 keep the more permissive policy by default for backwards compatibility.
