MinIO Operator STS is a native IAM Authentication for Kubernetes. Prior to version 7.1.0, if no audiences are provided for the `spec.audiences` field, the default will be of the Kubernetes apiserver. Without scoping, it can be replayed to other internal systems, which may unintentionally trust it. This issue has been patched in version 7.1.0.
