Privilege Escalation in Kubernetes
Quick fix
GHSA-33c5-9fx5-fvjm — k8s.io/apimachinery: upgrade to the fixed version with the command below.
go get k8s.io/apimachinery@v0.16.13Details
The Kubernetes kube-apiserver in versions v1.6-v1.15, and versions prior to v1.16.13, v1.17.9 and v1.18.7 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.
