The MongoDB user credentials are baked into the shipped JavaScript, so the author retains read access to every installer's linked WhatsApp session state — sufficient to hijack the linked WhatsApp account. The relay is not disclosed in the README, which only instructs the user to run npm start. The tarball additionally ships offensive tooling aimed at third-party WhatsApp users (a ~150-entry proxy pool in dist/proxies.cjs, batched reaction and socket-spoof flooding in dist/react-engine.cjs, and abuse commands such as perm-ban-num, cortana-ios-crash, realban, massreport); this is operator-directed abuse capability, separate from the installer-side session exfiltration.\n","state":0,"publishedAt":"2026-09-30T04:15:59+00:00","modifiedAt":"2026-09-30T10:32:25.4830942+00:00","affected":[{"ecosystem":"npm","name":"cortana-md-engine","ranges":[],"versions":["1.4.6"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/cortana-md-engine/v/1.4.6"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17323","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17323","identifiers":["MAL-2026-17323"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
