What is MAL-2026-16069?
MAL-2026-16069 is a malicious package in reactlogo-load, published on 9 Sep 2026.
Official description
The package presents itself as a logo/color utility but its exported loadLogo() function extracts a URL from LSB-encoded bits of a PNG, fetches the response body, and executes it via a reflective Function-constructor invocation. The 'constructor' property name and the Function reference are hidden behind a deterministic string-shuffle helper (hsvMean) named as a color utility, so no plaintext 'constructor', 'Function', 'eval', or destination URL appears in the source. runInContext binds global.require, module, and exports into the executed script, giving the fetched code full Node runtime capability on the caller's host. Following the README's documented usage (vite/tailwind build integration) triggers the fetch-and-execute path, so arbitrary attacker-controlled code runs on any machine that adopts this library.
What should I do about MAL-2026-16069?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
