Whatever bytes that server returns execute at npm install time with full Node privileges on the installer's machine. The advertised purpose (\"Native asset loader bridge for Fabric mod environments\") does not match the code: lib/renderer.js is an inert stub with no-op exports, and index.js contains only the remote fetch-and-eval loader. The package name evokes the unrelated Fabric Minecraft mod ecosystem, which is a cover story. The remote host controls the payload and can change it at any time, so installer impact is unbounded and can include credential theft, persistence, or lateral movement.\n\n---\n\nCredit: OpenSSF (source)","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.403Z","source_updated_at":"2026-10-01T06:31:28.000Z","source_disclosed_at":"2026-09-30T03:31:46.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T23:13:24.290Z"}],"next_cursor":null,"snapshot_revision":"42594"}
