The npm account testneo7755 published it on 2026-10-05 and it was unpublished about two minutes later; the same account published with-cte the same day with the same index.js and a different Collaborator subdomain.\n\n---\n_-= Per source details.

The destination is an out-of-band interaction server not associated with any declared publisher or documented package purpose, and the exfiltration fires automatically on default install without user interaction.\n","state":0,"publishedAt":"2026-10-05T09:02:39+00:00","modifiedAt":"2026-10-07T06:30:05.4433634+00:00","affected":[{"ecosystem":"npm","name":"checkmate-remediation-assistant","ranges":[],"versions":["1.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/checkmate-remediation-assistant/v/1.0.0","https://www.npmjs.com/package/checkmate-remediation-assistant"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17572","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17572","identifiers":["MAL-2026-17572"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
