The package's declared purpose (a Fastify client bundler / Tailwindcss forms bundler) and CDN-style helpers (setDefaultModule constructing cdnjs URLs) are unused decoys; the actually-invoked network path targets the bare IP. Bundled runtime dependencies (@primno/dpapi, better-sqlite3, node-machine-id) are consistent with a Windows credential/wallet stealer that a delivered payload would load through the injected `require`.\n","state":0,"publishedAt":"2026-08-05T13:01:48+00:00","modifiedAt":"2026-09-24T09:30:14.7198826+00:00","affected":[{"ecosystem":"npm","name":"fastify-client-bundler","ranges":[],"versions":["1.4.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/fastify-client-bundler/v/1.4.0"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-12379","license":"OSV · upstream source license applies","key":"osv:MAL-2026-12379","identifiers":["MAL-2026-12379"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
