SCA: security update for faye-websocket (GHSA-2v5c-755p-p4gv)

high Tenable Self-Hosted Container Security Plugin ID 409098

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In faye-websocket before version 0.11.0, there is a lack of certification validation in TLS handshakes.
 The `Faye::WebSocket::Client` class uses the `EM::Connection#start_tls` method in EventMachine to
 implement the TLS handshake whenever a `wss:` URL is used for the connection. This method does not
 implement certificate verification by default, meaning that it does not check that the server presents a
 valid and trusted TLS certificate for the expected hostname. That means that any `wss:` connection made
 using this library is vulnerable to a man-in-the-middle attack, since it does not confirm the identity of
 the server it is connected to. For further background information on this issue, please see the referenced
 GitHub Advisory. Upgrading `faye-websocket` to v0.11.0 is recommended. (CVE-2020-15133)
