What is CVE-2017-1000209?

The Java WebSocket client, nv-websocket-client, fails to ensure that the server's hostname corresponds with the domain name specified in the X.509 certificate's Common Name (CN) or subjectAltName field. This oversight permits potential man-in-the-middle attackers to impersonate SSL/TLS servers through the use of any valid certificate, leading to serious security risks for applications utilizing this library.
