Official description
The package name typosquats TensorFlow.js and its npm postinstall lifecycle script collects installer host identifiers (hostname, platform, arch, Node.js version, package name) and POSTs them as JSON to the hardcoded third-party host zl2u2d1x.instances.poc.jchunt.top at path /tfjs-inference. The exfiltration fires automatically on
npm install with no opt-in and no configuration. Internal comments self-label the package as a security research canary, but the destination is author-controlled and the installer receives no notice or consent prompt.What should I do about MAL-2026-14192?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
