The stream-protocol equivalent (rabbit_stream_reader.erl create_super_stream handler) calls rabbit_stream_utils:check_super_stream_management_permitted\/4 which enforces configure on the exchange and each partition queue. The HTTP handler omits this call entirely. A user with management tag and vhost access , but no configure permission on any resource , can create super-streams (an exchange + N partition stream queues + bindings) via the HTTP API. The native stream-protocol path enforces configure on each resource; the HTTP path does not, creating a privilege escalation from &#8216;can view&#8217; to &#8216;can create persistent cluster-wide resources.&#8217; Preconditions include rabbitmq_stream_management plugin enabled management tag + vhost access (no resource permissions needed).
