services / Azure / Kubernetes ClusterRoles

A ClusterRole is a cluster-scoped Kubernetes RBAC object that defines a named set of permissions (verbs over API resources) that can be bound to subjects cluster-wide via ClusterRoleBindings.

ClusterRoles define the permission sets behind every cluster-wide grant (the analog of Azure roleDefinitions); they can encode cluster-admin, so the asset is cluster-wide access-control policy.

Creating or updating a ClusterRole lets an attacker inject arbitrary cluster-wide permissions into a role definition, escalating the privileges of every subject already bound to that role.

Risks

1. Privilege escalation (CRITICAL)

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.
