Each listed version (99.0.1, 3.0.0) 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.

Its only runtime behavior is a beacon in beacon.cjs that fires both from the npm postinstall lifecycle hook and on require() via index.js. The beacon collects the installer's OS hostname, __dirname install path, and process.cwd() (which commonly embed the Unix username and internal project/repo names) along with Node version, and POSTs them as JSON to the hardcoded plaintext bare-IP endpoint http://185.158.107.175:8787/_ah/dc with an x-beacon-package header identifying the resolving package. The scoped name @greenlake/* mimicking an internal namespace, the inert public API, and the automatic callback to a hardcoded bare-IP operator on install and import together match the shape of a dependency-confusion probe: resolving this package on an installer's machine silently discloses internal host, user, path, and namespace information to an external operator the installer did not opt into.\n","state":0,"publishedAt":"2026-10-23T21:31:58+00:00","modifiedAt":"2026-10-26T06:00:04.2084437+00:00","affected":[{"ecosystem":"npm","name":"@greenlake/common-context","ranges":[],"versions":["99.0.1","3.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@greenlake/common-context/v/99.0.1","https://www.npmjs.com/package/@greenlake/common-context","https://www.npmjs.com/package/@greenlake/common-context/v/3.0.0"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-18282","license":"OSV · upstream source license applies","key":"osv:MAL-2026-18282","identifiers":["MAL-2026-18282"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
