The combination of import-time execution, platform-gated branching, remote HTTPS fetch, and subprocess execution inside a file whose contents are deliberately concealed matches the fetch-and-execute dropper shape. A terminal color/title formatter has no functional need for child_process or outbound HTTPS at import time, and the obfuscation hides the destination host and the command handed to execFile. Any downstream package that requires or imports chromatitle triggers this loader on load.\n","state":0,"publishedAt":"2026-09-25T02:32:12+00:00","modifiedAt":"2026-09-25T03:00:07.5231591+00:00","affected":[{"ecosystem":"npm","name":"chromatitle","ranges":[],"versions":["1.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/chromatitle/v/1.0.0"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17173","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17173","identifiers":["MAL-2026-17173"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
