Each listed version (1.0.0, 1.0.1, 2.0.1, 0.0.1, 3.0.0, 1.1.0, 99.0.1, 2.0.0) 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.

On execution it collects host identifiers (hostname, install path, current working directory, Node.js version) and POSTs them to a hardcoded bare-IPv4 endpoint over plaintext HTTP at http://185.158.107.175:8787/_ah/dc. The destination is not a publisher-owned domain. The package's `index.js` exports a `Proxy` that returns no-op functions for every property access, so the module provides no real functionality — its only effect on install or import is the beacon callback. The combination of a non-functional shim under an organisation-shaped scope with a reconnaissance beacon fired at install and import time is the fingerprint of a dependency-confusion / namesquat probe that reports successful resolution and build inside a victim's environment.\n","state":0,"publishedAt":"2026-10-25T14:21:12+00:00","modifiedAt":"2026-10-26T03:30:06.165205+00:00","affected":[{"ecosystem":"npm","name":"@ppa-web-components/ppa-searchform","ranges":[],"versions":["0.0.1","2.0.1","3.0.0","99.0.1","2.0.0","1.0.1","1.0.0","1.1.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@ppa-web-components/ppa-searchform/v/0.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-searchform/v/2.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-searchform/v/3.0.0","https://www.npmjs.com/package/@ppa-web-components/ppa-searchform/v/99.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-searchform/v/2.0.0","https://www.npmjs.com/package/@ppa-web-components/ppa-searchform/v/1.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-searchform/v/1.0.0","https://www.npmjs.com/package/@ppa-web-components/ppa-searchform/v/1.1.0","https://www.npmjs.com/package/@ppa-web-components/ppa-searchform"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-18287","license":"OSV · upstream source license applies","key":"osv:MAL-2026-18287","identifiers":["MAL-2026-18287"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
