Insecure defaults due to CORS misconfiguration in socket.io
The package socket.io before 2.4.0 are vulnerable to Insecure Defaults due to CORS Misconfiguration. All domains are whitelisted by default.
security: do not allow all origins by default (f78a575)
properly overwrite the query sent in the handshake (d33a619)
:warning: BREAKING CHANGE :warning:
Previously, CORS was enabled by default, which meant that a Socket.IO server sent the necessary CORS headers (Access-Control-Allow-xxx) to any domain. This will not be the case anymore, and you now have to explicitly enable it.
