The destination is not the installer's own infrastructure and is not caller-configurable. The `@coopeuch` scope combined with the 1.999.999 version has the shape of dependency-confusion targeting of a specific organization's internal namespace, in which `npm install` resolves this public package in place of an intended internal one and emits the fingerprint to the author's collector.\n\n---\n\nCredit: OpenSSF ([source](https://github.com/o","public_affected_ranges":["= 1.999.999"]}],"null_published_at":"2026-10-31T22:13:39.932Z","source_updated_at":"2026-10-11T15:31:13.000Z","source_disclosed_at":"2026-10-11T15:31:11.000Z","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":"2026-10-31T22:07:01.069Z"}],"next_cursor":null,"snapshot_revision":"42594"}
