TCP 8081
Synopsis
- Sonatype Nexus Repository Manager (v3) serves its web UI and APIs on TCP 8081 by default.
- Apache Flink exposes its JobManager web dashboard on TCP 8081 by default.
- React Native’s Metro bundler (including Expo workflows) listens on TCP 8081 during development.
- JFrog Platform: the Access service listens on TCP 8081 by default; many older Artifactory installations also used 8081 for the main UI/API.
- mongo-express (MongoDB admin UI) defaults to TCP 8081.
- Motion (the motion-project CCTV software) uses TCP 8081 by default for its MJPEG camera stream.
- Eclipse Mosquitto MQTT brokers are commonly deployed with a WebSocket-over-TLS listener on TCP 8081 (per standard example configs).
- Attackers frequently scan TCP 8081 for exposed admin/dev services (notably Nexus/Artifactory/Metro), and outdated versions have had vulnerabilities leading to unauthenticated access or remote code execution.
