browser-metrics-plugin.contrib@1.1.0

browser-metrics-plugin.contrib is a dependency-confusion package: it is described as a "Compatibility shim", uses version numbers up to 99.0.1, and its README calls it an "authorized dependency-confusion test". Each listed version has a postinstall script that runs `node beacon.cjs` on npm install, and index.js calls the same code when the package is imported; it POSTs the hostname, install path and current working directory over plain HTTP to `http://185.158.107.175:8787/_ah/dc`, and index.js exports a Proxy that returns no-op functions so builds importing the real package keep running. The npm account xwise8887 published these 6 versions, and 7 versions of troubleshooting with the same payload, on 2026-10-07 between 00:01 and 00:07 UTC.
