Affected versions of nes are vulnerable to denial of service when given an invalid cookie header, and websocket authentication is set to cookie. Submitting an invalid cookie on the websocket upgrade request will cause the node process to throw and exit.

Recommendation

Update to version 6.4.1 or later.
