JavaScript Framework Version Exposed

Your frontend framework version (React, Vue, Angular, jQuery, etc.) is detectable via source code patterns, global variables, or library files.

Risk

While less critical than server-side exposure, known frontend framework versions can reveal client-side vulnerabilities. Outdated jQuery versions have known XSS vulnerabilities. Old Angular versions may have template injection issues. Attackers can craft payloads specifically for your framework version.

Solution

Keep your frontend dependencies updated. Use bundled/minified builds that strip version comments. Avoid loading libraries from CDNs with version numbers in the URL.

Example

# Update dependencies regularly
npm audit
npm update

Snyk - Vulnerability Database npm audit
