A security issue was discovered in Kubernetes where a user that can create
pods and persistent volumes on Windows nodes may be able to escalate to
admin privileges on those nodes. Kubernetes clusters are only affected if
they are using an in-tree storage plugin for Windows nodes.

Notes

Author Note
leosilva kubernates is in fact a kubernetes installer that calls snap, not the package it self.
