In today’s web-driven world, your application’s performance and its security often depends on the third-party libraries you use. But what if those libraries are outdated, vulnerable, or even compromised?
That’s where VWrap Scanner’s JavaScript Library Scanner comes in a powerful feature engineered to detect vulnerable, deprecated, or malicious JavaScript libraries lurking in your frontend code. Whether you’re running a SaaS platform, e-commerce store, or a high-traffic web app, this feature is your first line of defense against client-side attacks.
The JavaScript Library Scanner is a specialized module within VWrap Scanner that automatically scans your website or application for third-party JavaScript dependencies. It identifies the exact version of each library and cross-checks it against a real-time CVE (Common Vulnerabilities and Exposures) database.
This allows you to:
Detect outdated or unpatched versions of popular JS frameworks like jQuery, React, Angular, Vue.js, Lodash, etc.
Highlight known vulnerabilities such as XSS (Cross-Site Scripting), prototype pollution, and remote code execution (RCE).
Monitor for libraries hosted via CDN that might have been tampered with.
Let’s say you’re running a healthcare appointment portal using jQuery 1.12.4. That version contains a prototype pollution vulnerability (CVE-2020-11022). If an attacker exploits this, they could manipulate internal object structures, potentially hijacking user sessions or triggering unauthorized actions.
VWrap Scanner’s JavaScript Library Scanner would catch this during its next scan, flag it as critical, and suggest upgrading to a patched version (e.g., jQuery 3.6.0).That’s proactive defense, not reactive cleanup.
