The package git before 1.11.0 are vulnerable to Command Injection via git argument injection. When calling the fetch(remote = 'origin', opts = {}) function, the remote parameter is passed to the git fetch subcommand in a way that additional flags can be set. The additional flags can be used to perform a command injection.
