https://notcve.org/view.php?id=CVE-2022-3162
18 Jan 2023 — Users authorized to list or watch one type of namespaced custom resource cluster-wide can read custom resources of a different type in the same API group without authorization. Clusters are impacted by this vulnerability if all of the following are true: 1. There are 2+ CustomResourceDefinitions sharing the same API group 2. Users have cluster-wide list or watch authorization on one of those custom resources. 3. The same users are not authorized to read another custom resource in the same API group. • https://github.com/kubernetes/kubernetes/issues/113756 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-23: Relative Path Traversal •

CVE-2020-8562 – Bypass of Kubernetes API Server proxy TOCTOU
https://notcve.org/view.php?id=CVE-2020-8562
01 Feb 2022 — As mitigations to a report from 2019 and CVE-2020-8555, Kubernetes attempts to prevent proxied connections from accessing link-local or localhost networks when making user-driven connections to Services, Pods, Nodes, or StorageClass service providers. As part of this mitigation Kubernetes does a DNS name resolution check and validates that response IPs are not in the link-local (169.254.0.0/16) or localhost (127.0.0.0/8) range. Kubernetes then performs a second DNS resolution without validation for the actu... • https://github.com/kubernetes/kubernetes/issues/101493 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

CVE-2020-8561 – Webhook redirect in kube-apiserver
https://notcve.org/view.php?id=CVE-2020-8561
20 Sep 2021 — A security issue was discovered in Kubernetes where actors that control the responses of MutatingWebhookConfiguration or ValidatingWebhookConfiguration requests are able to redirect kube-apiserver requests to private networks of the apiserver. If that user can view kube-apiserver logs when the log level is set to 10, they can view the redirected responses and headers in the logs.

CVE-2021-25735 – Validating Admission Webhook does not observe some previous fields
https://notcve.org/view.php?id=CVE-2021-25735
28 Jul 2021 — 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.

CVE-2021-25736 – Windows kube-proxy LoadBalancer contention
https://notcve.org/view.php?id=CVE-2021-25736
23 Jun 2021 — Kube-proxy on Windows can unintentionally forward traffic to local processes listening on the same port (“spec.ports[*].port”) as a LoadBalancer Service when the LoadBalancer controller does not set the “status.loadBalancer.ingress[].ip” field. Clusters where the LoadBalancer controller sets the “status.loadBalancer.ingress[].ip” field are unaffected.
