services / Azure / Kubernetes role bindings (Arc connected cluster)

RoleBinding objects in the Kubernetes RBAC API of an Azure Arc connected cluster. They grant the permissions of a (cluster)role to specific subjects (users, groups, service accounts) within a namespace.

RoleBindings are the assignment graph mapping identities to permissions; modifying them directly changes who holds what access in the cluster.

Creating or updating a RoleBinding binds a role (including a ClusterRole) to an attacker-chosen subject, directly granting elevated privileges to a controlled identity.

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.
