services / Azure / Kubernetes ClusterRoles (AKS Fleet member)

Kubernetes ClusterRole objects on a member cluster of an AKS Fleet. ClusterRoles define cluster-wide permission sets (verbs over resources) that bindings can grant to subjects.

Cluster-wide RBAC permission definitions; creating/expanding or binding them enables cluster-admin escalation, hence CRITICAL asset sensitivity.

Microsoft.​ContainerService/​fleets/​members/​rbac.​authorization.​k8s.​io/​clusterroles/​delete

Deleting ClusterRoles destroys cluster-wide RBAC permission definitions, breaking access-control policy and denying access to all principals whose bindings reference those roles.

Risks

1. Policy destruction (CRITICAL)
2. Denial-of-access (EVASION)

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.
