phantomjs-cheniu is a Headless WebKit with JS API phantomjs-cheniu downloads 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 resources with an attacker controlled copy if the attacker is on the network or positioned in between the user and the remote server.

Affected: npm: phantomjs-cheniu

Affected versions of `phantomjs-cheniu` 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 `phantomjs-cheniu`.

## Recommendation

No patch is currently available for this vulnerability.

As this package is just a fork of Medium's [`phantomjs-prebuilt`](https://github.com/Medium/phantomjs) package, the best mitigation is currently to install the `Medium` version of [`phantomjs-prebuilt`](https://github.com/Medium/phantomjs). This can be done via the following command: ``` npm i phantomjs-prebuilt ```
