Advisories for Npm/Ungit package

The package ungit before 1.5.20 is vulnerable to Remote Code Execution (RCE) via argument injection. The issue occurs when calling the /api/fetch endpoint. User controlled values (remote and ref) are passed to the git fetch command. By injecting some git options it was possible to get arbitrary command execution.

Due to the use of child_process.exec when executing git commands, ungit allows for commands to be injectied from user input fields that end up in an executed git command.
