Bumps [npm](https://github.com/npm/cli) from 6.10.1 to 6.13.4. **This update includes security fixes.**

<summary>Vulnerabilities fixed</summary>

*Sourced from The GitHub Security Advisory Database.*

> **Low severity vulnerability that affects npm**
> ## Unauthorized File Access
> 
> Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write. It is possible for packages to create symlinks to files outside of the`node_modules` folder through the `bin` field upon installation. A properly constructed entry in the package.json bin field would allow a package publisher to create a symlink pointing to arbitrary files on a user’s system when the package is installed.  
> 
> This behavior is possible through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.
> 
> Thank you Daniel Ruf for responsibly reporting the issue!
> 
> Further information: [npm blog post](https://blog.npmjs.org/post/189618601100/binary-planting-with-the-npm-cli)
> 
> Affected versions: < 6.13.3

> **Low severity vulnerability that affects npm**
> ## Arbitrary File Write
> 
> 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 modify and/or gain access to arbitrary files on a user’s system when the package is installed.

> **Low severity vulnerability that affects npm**
> ## Arbitrary File Overwrite
> 
> Versions of  the npm CLI prior to 6.13.4 are vulnerable to an Arbitrary File Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a `serve` binary, any subsequent installs of packages that also create a `serve` binary would overwrite the previous `serve` binary.  
> 
> This behavior is still allowed in local installations and also through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.
