morningstar-design-systemnpm

On npm install, the package's preinstall lifecycle script runs wget against a hardcoded bare-IP HTTP endpoint, passing the output of id, pwd, hostname, and ip a as URL query parameters. This leaks the installing user's username/UID/GID, working directory, hostname, and full network interface configuration to an attacker-controlled host automatically, before any other code runs. The package name targets Morningstar's organizational namespace and is published at an absurd 99.0.1 version — the canonical dependency-confusion shape designed to override an internal package of the same name. README self-identifies as a dependency-confusion PoC. Whether labeled research or not, the published artifact actively exfiltrates installer data to a third-party IP and is unsafe to install in any environment.
