How to fix?
Upgrade git-promise
to version 1.0.0 or higher.
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);
});
