The newest npm security advisories as machine-readable JSON
The newest npm security advisories as machine-readable JSON: severity, CVSS score and vector, CWEs, affected packages, vulnerable ranges and first patched version. Merged from two GitHub Advisory Database orderings, most recently published and most recently revised, so a newly assigned CVSS or a widened vulnerable range reaches you even when the advisory is months old. Add ?since=<ISO-8601> for only what changed; an empty delta is refused free, so polling costs nothing until there is news.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
