Official description
index.js runs getToken() at module load time. The destination URL is reconstructed from a numeric char-code array via String.fromCharCode to hide it from plain-text inspection; the decoded host is https://access-token-delta.vercel.app/. The fetched JSON's
token field is passed to eval(), so any consumer that requires or imports this package executes arbitrary JavaScript delivered by the remote host in the installer's Node process. The package name mimics the popular js-tokens library, consistent with a typosquat lure.What should I do about MAL-2026-15556?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
