selenium-binaries downloads resources over HTTP

Versions of selenium-binaries prior to 0.15.0 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 selenium-binaries.

Recommendation

A fix for this vulnerability is available on the master branch of the repository as part of version 0.15.0.

Another mitigation currently available is to use an alternate package, such as selenium-webdriver, the official selenium bindings for node.js.
