CVE-2016-10566
install-nw downloads Resources over HTTP
install-nw is a module which quickly and robustly installs and caches NW.js. install-nw versions below 1.1.5 download binary resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested binary with an attacker controlled binary if the attacker is on the network or positioned in between the user and the remote server.

GitHub AdvisoriesGHSA-wq7q-7vfh-2x3h
install-nw downloads Resources over HTTP
Affected versions of install-nw insecurely download an executable over an unencrypted HTTP connection.
In scenarios where an attacker has a privileged network position, it is possible to intercept the response and replace the executable with a malicious one, resulting in code execution on the system running install-nw.
Recommendation
Update to version 1.1.5 or later.
