If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

The package's package.json defines a postinstall lifecycle script that fetches a JavaScript file from a non-publisher host (gitflic.ru, proxied via web.archive.org, at the path /project/hellscripter/install-scripts/blob/raw?file=node.js) and pipes the response directly into node, executing arbitrary remote code on the installer's machine during npm install. The fetched code is unpinned, unverified, and controlled by a third-party account unrelated to the Angular project. The package name @angulaar/core resembles @angular/core, increasing the likelihood of accidental installation.
