A local user, by creating a ClusterCurator resource with a specific naming convention, can trigger the creation of a cluster-scoped ClusterRoleBinding. This allows the user to escalate their privileges from namespace-local access to cluster-wide control. This privilege escalation grants broad permissions, including the ability to access and manipulate secrets, manage cluster actions, and delete hosted clusters or node pools."

Implement Kubernetes Role-Based Access Control (RBAC) policies to limit `create` permissions for `clustercurators.cluster.open-cluster-management.io` resources to only trusted administrators or service accounts. Alternatively, deploy an admission controller to enforce that `metadata.name` and `metadata.namespace` fields are identical when `ClusterCurator` resources are created, preventing the vulnerable condition."
