Each listed version (0.0.1, 1.0.0, 1.0.1, 99.0.1, 2.0.1, 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. Do not edit below this line.=-_\n\n## Source: amazon-inspector (cc4615498b50aa4b5f39a8367c44e6a18d4a7272ae71235716a152b2933d5ddd)\nThe package is described as a 'Compatibility shim' and ships a stub Proxy-based main plus beacon.cjs. The package.json declares scripts.postinstall: 'node beacon.cjs', and the main entry also invokes the same fire() routine on require. On both triggers, beacon.cjs collects installer identifiers — os.hostname(), __dirname (install path), process.cwd(), process.version, and the package name — and POSTs them in cleartext to the hardcoded bare-IP endpoint http://185.158.107.175:8787/_ah/dc. The destination is not a registry, publisher, or any documented infrastructure; it is a plain-HTTP bare IP with no TLS. An inline source comment states that a build that completes and calls back is cleaner evidence, confirming the artifact's purpose is to signal successful resolution and execution on installer machines. Combined with a scoped name resembling an internal namespace and no real library functionality, this matches the dependency-confusion / namesquat callback-probe shape.\n","state":0,"publishedAt":"2026-10-25T14:22:59+00:00","modifiedAt":"2026-10-26T03:30:05.2274041+00:00","affected":[{"ecosystem":"npm","name":"@ppa-web-components/ppa-builder","ranges":[],"versions":["99.0.1","1.0.0","0.0.1","2.0.1","1.0.1","3.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@ppa-web-components/ppa-builder/v/99.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-builder/v/1.0.0","https://www.npmjs.com/package/@ppa-web-components/ppa-builder/v/0.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-builder/v/2.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-builder/v/1.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-builder/v/3.0.0","https://www.npmjs.com/package/@ppa-web-components/ppa-builder"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-18273","license":"OSV · upstream source license applies","key":"osv:MAL-2026-18273","identifiers":["MAL-2026-18273"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
