Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write. It fails to prevent access to folders outside of the intended node_modules folder through the bin field. A properly constructed entry in the package.json bin field would allow a package publisher to create files on a user's system when the package is installed. It is only possible to affect files that the user running `npm install` has access to and it is not possible to over write files that already exist on disk.

This behavior is still possible through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.

## Recommendation

Upgrade to version 6.13.3 or later.
