  "whatItIs": "Atlassian's installation guide states that Confluence runs on port 8090 by default and that the installer prompts for another port if it is taken. The listener is the bundled Tomcat, so a 8090 on a server with Java processes is usually a wiki. IANA registers 8090/tcp to opsmessaging, a vehicle-to-station messaging assignment you will not encounter. Confluence is normally fronted by a reverse proxy on 80/443, with 8090 left bound to all interfaces underneath.",
  "exposure": {
    "verdict": "careful",
    "note": "Confluence has a long history of critical pre-auth vulnerabilities; expose it only through a proxy on a patched version, never as a bare 8090."
