services / Azure / Kubernetes role bindings (AKS Fleet)

Kubernetes RoleBinding objects in an AKS Fleet cluster, which grant the permissions of a Role or ClusterRole to subjects (users, groups, service accounts) within a namespace.

RoleBindings are the access-control grants that map identities to RBAC roles; creating them can bind a controlled identity to cluster-admin, an access-control asset treated as CRITICAL.

Creating/updating a RoleBinding binds a (possibly admin) role to an attacker-controlled subject, the canonical RBAC privilege-escalation primitive.

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.
