Each listed version (3.0.0, 1.0.1, 2.0.0, 1.1.0, 0.0.1, 2.0.1, 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 an unrelated bare IP over cleartext HTTP, not any publisher-controlled or registry infrastructure, and the shipped stub has no functional purpose other than the beacon. The scoped-name + stub + install-time recon beacon shape is consistent with a dependency-confusion recon callback used to identify internal build environments that resolved this public name.\n","state":0,"publishedAt":"2026-10-25T14:25:32+00:00","modifiedAt":"2026-10-26T03:30:05.231058+00:00","affected":[{"ecosystem":"npm","name":"@ppa-web-components/ppa-banner","ranges":[],"versions":["2.0.0","2.0.1","1.0.0","1.0.1","0.0.1","1.1.0","3.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@ppa-web-components/ppa-banner/v/2.0.0","https://www.npmjs.com/package/@ppa-web-components/ppa-banner/v/2.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-banner/v/1.0.0","https://www.npmjs.com/package/@ppa-web-components/ppa-banner/v/1.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-banner/v/0.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-banner/v/1.1.0","https://www.npmjs.com/package/@ppa-web-components/ppa-banner/v/3.0.0","https://www.npmjs.com/package/@ppa-web-components/ppa-banner"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-18272","license":"OSV · upstream source license applies","key":"osv:MAL-2026-18272","identifiers":["MAL-2026-18272"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
