add two recon modules detecting exposed kafka management consoles that ship without authentication by default: - kafka-ui-exposure (high): probes /api/clusters on a kafbat/provectus kafka ui and matches the kafka-ui-specific defaultCluster/brokerCount keys plus the online/offline/initializing status enum; an open instance leaks the cluster topology and lets an unauthenticated session browse and produce records, while a login- or oauth-protected instance returns 401 and is not flagged - kafdrop-exposure (high): probes / with an Accept: application/json header and matches the ClusterInfoVO summary/preferredReplicaPercent/brokers/topics shape; an open instance discloses broker hostnames, topics and messages, while an instance with the optional basic auth returns 401 both modules carry hard-test coverage with cross false-positive guards both ways, non-enum-status and missing-key negative cases, a wire-level check that the kafdrop module sends the Accept header, and 401 secured-instance cases
