Each listed version 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 xwise8887 published these 7 versions, and 6 versions of browser-metrics-plugin.contrib with the same payload, on 2026-10-07 between 00:01 and 00:07 UTC.\n\n---\n_-= Per source details.

The README self-labels the package as an authorized dependency-confusion test, but the behavior is identical to a dependency-confusion exfiltration payload: any environment whose internal/private package name collides with `troubleshooting` on the public npm registry will have its build host, install path, working directory, and Node version reported to an outside party at a bare IP, providing actionable fingerprinting of internal build systems and CI runners.\n","state":0,"publishedAt":"2026-10-07T00:04:15+00:00","modifiedAt":"2026-10-08T04:00:05.4521285+00:00","affected":[{"ecosystem":"npm","name":"troubleshooting","ranges":[],"versions":["0.1.0","1.0.0","1.0.1","99.0.1","3.0.0","1.1.0","2.0.1"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/troubleshooting","https://www.npmjs.com/package/troubleshooting/v/1.0.1","https://www.npmjs.com/package/troubleshooting/v/3.0.0","https://www.npmjs.com/package/troubleshooting/v/2.0.1","https://www.npmjs.com/package/troubleshooting/v/1.1.0","https://www.npmjs.com/package/troubleshooting/v/0.1.0","https://www.npmjs.com/package/troubleshooting/v/1.0.0","https://www.npmjs.com/package/troubleshooting/v/99.0.1"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17641","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17641","identifiers":["MAL-2026-17641"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
