index.js, the package main, issues a fetch to the hardcoded third-party collector https://webhook.site/ce5b0917-ae74-44c3-8a62-8a4e5003d44d with URL-encoded contents of document.documentElement.outerHTML (truncated to 4000 characters) appended as a query parameter. The call fires at require/import time in any environment where document and fetch exist (browser bundles, jsdom, Electron), silently exfiltrating page DOM — including any secrets, tokens, or user data rendered into the page — to an attacker-controlled webhook collector. The package has no declared purpose and an empty description. package.json additionally declares a self-dependency on zxcvb90-utils-helper with an unpinned pre-release range (^0.0.0-stage), so npm install resolves and installs whatever bytes the registry currently serves for that tag, with no integrity pin.
