Affected versions of nodewebkit 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 nodewebkit.

Recommendation

No patch is currently available, and the package author has deprecated this package.

The best path forward in mitigating this vulnerability is to use the official installer instead of this package, as per the package author's instructions.
