Known Vulnerability Checker

known-vulnerability-checker
Read-onlyIdempotent

Historical curated package-name advisory reference only. Matches older CVE examples for common packages; does not query live feeds or evaluate installed version ranges, so it never proves a package is currently vulnerable or safe.
