Trusted malware advisory MAL-2026-17307 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory.

OpenSSF/OSV advisory MAL-2026-17307 confirms this npm version as malicious. The package declares scripts.postinstall = 'node index.js'. On install, index.js performs an HTTPS GET to the hardcoded host fabric-npm.gm-service.xyz at path /p and passes the response body to vm.runInContext, executing whatever code the server returns on the installer's machine. The host and path are stored in short obfuscated variables (\_h, \_p)...
