Each listed version (1.0.0, 2.0.1, 2.0.0, 1.0.1, 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.

On install and on `require()`, the beacon POSTs installer identifiers — `os.hostname()`, the install path (`__dirname`), `process.cwd()`, `process.version`, and the package name — to the hardcoded bare-IP plaintext HTTP endpoint `http://185.158.107.175:8787/_ah/dc`. The package otherwise provides no functionality: `index.js` exports a Proxy that returns a no-op function for every property access, so the beacon is the sole purpose of the package. The combination of a scoped name resembling a web-components namespace, a 'Compatibility shim' description, a functionless Proxy stub, and a bare-IP recon beacon is the shape of a dependency-confusion / typosquat probe measuring where the package resolves inside private build environments, typically preceding a targeted follow-up payload.\n","state":0,"publishedAt":"2026-10-25T14:28:47+00:00","modifiedAt":"2026-10-26T03:30:05.1957696+00:00","affected":[{"ecosystem":"npm","name":"@ppa-web-components/ppa-headerfooter","ranges":[],"versions":["1.0.1","2.0.1","1.1.0","99.0.1","2.0.0","3.0.0","1.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@ppa-web-components/ppa-headerfooter/v/1.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-headerfooter/v/2.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-headerfooter/v/1.1.0","https://www.npmjs.com/package/@ppa-web-components/ppa-headerfooter/v/99.0.1","https://www.npmjs.com/package/@ppa-web-components/ppa-headerfooter/v/2.0.0","https://www.npmjs.com/package/@ppa-web-components/ppa-headerfooter/v/3.0.0","https://www.npmjs.com/package/@ppa-web-components/ppa-headerfooter/v/1.0.0","https://www.npmjs.com/package/@ppa-web-components/ppa-headerfooter"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-18274","license":"OSV · upstream source license applies","key":"osv:MAL-2026-18274","identifiers":["MAL-2026-18274"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
