Technical Details

what runs on :48653

Robot Raconteur provides service-oriented communication: clients connect to named services and exchange requests, responses, and events using service definitions. TCP on port 48653 is the usual path for service communication, commonly addressed with a Robot Raconteur TCP URL; UDP is used for discovery-related communication. TLS can be configured, but traffic should not be assumed encrypted unless the deployment enables it. The port is assigned by IANA to Robot Raconteur and Wason Technology LLC.

security overview

A reachable service may expose robot or automation functions and data; the impact depends on the service's configured authentication and permissions. Do not expose it directly to the internet: restrict access to trusted networks, enable appropriate authentication and TLS, and review which operations the service permits. No specific vulnerability is implied by the port assignment.
