Each listed version (3.0.0, 1.0.0) 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 wiseke published 14 such packages under the @greenlake, @sxm-web, @drone-js-ext and @ppa-web-components scopes between 2026-10-23 21:23 and 2026-10-25 14:28 UTC; index.js is byte-identical to that of ph-common (MAL-2026-1809), which sends to the same endpoint.","affected":[{"package":{"name":"@greenlake/context-pane","ecosystem":"npm","purl":"pkg:npm/%40greenlake/context-pane"},"versions":["3.0.0","1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@greenlake/context-pane/MAL-2026-18317.json"}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@greenlake/context-pane"}],"database_specific":{"iocs":{"files":[{"digests":{"sha256":"a86a4da763bbb34c16f361abe7aab66d5df591b66867ac8160041f932159b08d"},"note":"Main entry point; calls beacon.cjs fire() on import and exports a no-op Proxy.
