Known Vulnerable JavaScript Libraries
Scans loaded frontend scripts (jQuery, Lodash, Moment, Bootstrap) against Retire.js vulnerability databases.
Why It Matters
Using vulnerable library versions allows attackers to exploit prototype pollution, regex denial of service, or DOM XSS.
How We Check This
We detect library versions using script hash signatures and regex patterns, then match against the National Vulnerability Database (NVD).
How to Fix & Implement
Copy-paste configuration blocks tailored for your web server or edge proxy.

Frequently Asked Questions
How do outdated libraries introduce XSS?
