Official description
index.js stores a remote URL and a
curl -sL -o command as numeric char-code arrays and reconstructs them at runtime with String.fromCharCode.apply, then fetches and executes the retrieved content at install/import time. Hiding the destination and the download-and-run command behind char-code obfuscation is inconsistent with any legitimate installer or SDK, which references URLs in plain form. The reconstructed shell invocation downloads an attacker-controlled payload to disk and runs it on the installer's machine, giving whoever published the package arbitrary code execution on any host that installs it.What should I do about MAL-2026-14250?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
