The Kubernetes API server must have Alpha APIs disabled.

Description

<VulnDiscussion>Kubernetes allows alpha API calls within the API server. The alpha features are disabled by default since they are not ready for production and likely to change without notice. These features may also contain security issues that are rectified as the feature matures. To keep the Kubernetes cluster secure and stable, these alpha features must not be used.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
