How to fix?

There is no fixed version for ggit.

Overview

Affected versions of this package are vulnerable to Arbitrary Argument Injection via the clone() API, which allows specifying the remote URL to clone and the file on disk to clone to. The library does not sanitize for user input or validate a given URL scheme, nor does it properly pass command-line flags to the git binary using the double-dash POSIX characters (--) to communicate the end of options.

PoC

const clone = require("ggit").cloneRepo;
clone({
  url: "--upload-pack=$(touch /tmp/pwned)",
  folder: "/tmp/dbd",
}).then(function () {
  console.log("cloned repo to destination folder");
});
