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.\n\n---\n_-= Per source details.

The destination is a bare IPv4 on a non-standard port, unrelated to any publisher infrastructure. The package has no advertised functionality: main exports a Proxy of no-op functions so that bundlers and consumers do not crash on property access, while the require-time path and the postinstall hook both exist solely to trigger the callback. The package self-describes as a 'Compatibility shim' with no legitimate reason to phone home, and the generic @greenlake/context-pane name combined with the no-op export surface is consistent with a dependency-confusion lure whose only effect on installers is the install-time and import-time beacon.\n","state":0,"publishedAt":"2026-10-23T21:33:13+00:00","modifiedAt":"2026-10-26T06:00:04.2106075+00:00","affected":[{"ecosystem":"npm","name":"@greenlake/context-pane","ranges":[],"versions":["3.0.0","1.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@greenlake/context-pane","https://www.npmjs.com/package/@greenlake/context-pane/v/1.0.0","https://www.npmjs.com/package/@greenlake/context-pane/v/3.0.0"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-18317","license":"OSV · upstream source license applies","key":"osv:MAL-2026-18317","identifiers":["MAL-2026-18317"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
