vue-demi-fix is a name-confusion package against the widely used vue-demi library. package.json declares both preinstall and postinstall lifecycle scripts that invoke curl against a hardcoded bare-IP HTTP endpoint (http://109.71.252.153:8080/), exfiltrating the installer's OS, username (whoami), current working directory (pwd), and hostname as URL query parameters on every npm install. The package ships no real functionality — index.js only prints a proof-of-concept notice and README self-labels as a 'Responsible Disclosure' PoC. Regardless of the PoC framing, installers receive no benign function and their host identity is unconditionally beaconed to a non-publisher, non-registry endpoint on a default install.
