Query OSV.dev for known vulnerabilities affecting an npm package, optionally scoped to one exact version (e.g. to check whether a version pinned in a lockfile is safe). Returns isVulnerable and highestSeverity as a direct answer, plus each finding's severity, a plain-language summary, CVE aliases, and the fixedVersion to upgrade to — not a raw advisory dump. Also cross-checks the name/version against the npm registry: isVulnerable:false on a package that does not actually exist there (typo, wrong ecosystem) would otherwise look identical to a genuinely clean result — see packageExists/existenceCheckNote. A name or version not found on the registry does NOT discard already-fetched OSV data or short-circuit into an error: OSV/GHSA advisory data is independent of the package's current registry listing, and a package/version pulled from npm for being malicious (unpublished/yanked) is exactly the case where real vulnerability data must still be reported, not hidden behind a 404. Use before recommending, installing, or upgrading a package.
