services / Azure / Kubernetes service accounts (fleet)

Kubernetes ServiceAccount objects within an AKS fleet namespace, which represent in-cluster workload identities that pods authenticate as and that are bound to RBAC roles.

Workload identities are targets for impersonation and credential theft; controlling them enables persistence and privilege escalation across the cluster.


Microsoft.​ContainerService/​fleets/​serviceaccounts/​delete

Deleting ServiceAccounts removes cluster workload identities, destroying accounts and breaking authentication for the pods that depend on them, disrupting those services.

Risks

Scope: CRITICAL

This privilege may grant access to sensitive data from a significant fraction of organizational functions, allow interruption of critical organizational services, or its exploit could lead to significant privilege escalation.
