This is a DNS-based exfiltration beacon: installing the package transmits installer host identifiers to a non-first-party canary domain over DNS resolution at install time. The version number 99.99.99 and package name shape are consistent with a dependency-confusion lure targeting an internal package name.\n","state":0,"publishedAt":"2026-09-17T23:12:41+00:00","modifiedAt":"2026-09-17T23:30:06.5102318+00:00","affected":[{"ecosystem":"npm","name":"test89078-auth","ranges":[],"versions":["99.99.99"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/test89078-auth/v/99.99.99"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-16271","license":"OSV · upstream source license applies","key":"osv:MAL-2026-16271","identifiers":["MAL-2026-16271"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
