What is MAL-2026-17537?
MAL-2026-17537 is a malicious package in @angulaar/core, published on 5 Oct 2026.
Official description
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.
What should I do about MAL-2026-17537?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
