The Kubernetes Controller Manager must create unique service accounts for each work payload.

Description

<VulnDiscussion>The Kubernetes Controller Manager is a background process that embeds core control loops regulating cluster system state through the API Server. Every process executed in a pod has an associated service account. By default, service accounts use the same credentials for authentication. Implementing the default settings poses a High risk to the Kubernetes Controller Manager. Setting the "--use-service-account-credential" value lowers the attack surface by generating unique service accounts settings for each controller instance.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
