Improper input validation in the Kubernetes API server in versions
v1.0-1.12 and versions prior to v1.13.12, v1.14.8, v1.15.5, and v1.16.2
allows authorized users to send malicious YAML or JSON payloads, causing
the API server to consume excessive CPU or memory, potentially crashing and
becoming unavailable. Prior to v1.14.0, default RBAC policy authorized
anonymous users to submit requests that could trigger this vulnerability.
Clusters upgraded from a version prior to v1.14.0 keep the more permissive
policy by default for backwards compatibility.

Notes

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