Question

I recently updated my version of angular using ng update and when running npm audit it found 1 high severity vulnerability but offered no suggestions on how to resolve it. It usually suggests to upgrade a package from package.json like: "angular-devkit/build-angular" but I am already using their latest version.

                   === npm audit security report ===

I thought of installing npm i tar but I am not sure.

Answer 1

angular-cli relies on node-gyp , who have an open issue for this: https://github.com/nodejs/node-gyp/issues/1714

To work around, you can patch node-gyp and then patch angular to use your patched node-gyp. Or wait and hope that they will fix it soon.

Answer 2

The following worked for me:

Go to node_modules > node_gyp > package.json, then locate tar under dependencies and replace 2.0.0 with 4.4.8.

Then run:

1. npm i
2. npm audit
3. npm audit fix
4. npm audit

you should see 0 vulnerabilities.

I've updated a few angular projects and each project had the same issue. Doing the above worked all the time.

Answer 3

You should search in your package-lock.json this:

"tar": {
  "version": "2.2.1",
  "resolved": "https://registry.npmjs.org/tar/-/tar-2.2.1.tgz",

And reemplace for that:

"tar": {
  "version": "4.4.8",
  "resolved": "https://registry.npmjs.org/tar/-/tar-4.4.8.tgz",

That worked for me
