JavaScript security
audited instantly.
Kuality scans every JavaScript library loaded on your live site, matches detected versions against the CVE database, and flags known vulnerabilities in jQuery, React, Bootstrap, and hundreds of other packages — without access to your source code.
jQuery 1.11.3 has CVE-2019-11358 (CVSS 6.1 — prototype pollution). Upgrade to 3.7+.
What the JavaScript audit checks
Kuality loads your site in a real browser, captures every script that executes, fingerprints library versions, and cross-references against the NVD/CVE database.
Library Detection
Identifies JavaScript frameworks and libraries by version fingerprint — jQuery, React, Vue, Angular, Bootstrap, Lodash, and hundreds more, including minified builds.
CVE Database Matching
Matches every detected library version against the NIST National Vulnerability Database. Returns CVSS scores, CVE IDs, and links to advisories for every match.
Outdated Dependency Flagging
Flags libraries that are significantly behind the latest stable release, even if no active CVE has been assigned yet.
CDN-Loaded Scripts
Catches vulnerable libraries loaded from third-party CDNs (jsDelivr, cdnjs, unpkg) that your own dependency scanner never sees.
Scheduled Rescans
New CVEs are published daily. Schedule weekly JS audits so you're notified when a library you're already running becomes vulnerable — not when you remember to check.
Fix Guidance
Each finding includes the safe version to upgrade to, the attack vector, and whether the vulnerability is exploitable from client-side or requires server access.
JS security is one of 17 checks in Kuality
Run the JavaScript audit alongside security headers, SSL, cookie compliance, and accessibility — all in a single scan, tracked over time, with CI/CD quality gates.
