zoom-widget-xss-poc-pareshnpm

Package ships a single browser-side IIFE (index.js) that manipulates the DOM (inserts a banner into #root and calls window.widgetSend with a demonstration payload) when loaded as a <script> tag inside a third-party web widget. package.json declares no preinstall/install/postinstall/prepare lifecycle scripts, and the module performs no filesystem access, no network I/O, and no credential reads under Node. The referenced globals (document, window) are undefined when the module is required, so installing or requiring the package does not execute the PoC. The package is documented as a security-research proof-of-concept and does not target the installer.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
