Intra-cluster communication does not use TLS. The services within the NGINX Controller 3.x before 3.4.0 namespace are using cleartext protocols inside the cluster.
The software transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
