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 •
