NVD Description

Note: Versions mentioned in the description apply only to the upstream terraform-1.8 package and not the terraform-1.8 package as distributed by Chainguard.

The Kubernetes kube-apiserver in versions v1.6-v1.15, and versions prior to v1.16.13, v1.17.9 and v1.18.6 are vulnerable to an unvalidated redirect on proxied upgrade requests that could allow an attacker to escalate privileges from a node compromise to a full cluster compromise.
