The version number 99.99.99 combined with the beacon shape is the canonical dependency-confusion probe pattern used to detect resolution of an internal package name against a public registry. The package ships no legitimate library functionality.\n","state":0,"publishedAt":"2026-09-21T03:24:04+00:00","modifiedAt":"2026-09-21T03:30:17.6268068+00:00","affected":[{"ecosystem":"npm","name":"test1sdsd2","ranges":[],"versions":["99.99.99"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/test1sdsd2/v/99.99.99"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-16316","license":"OSV · upstream source license applies","key":"osv:MAL-2026-16316","identifiers":["MAL-2026-16316"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
