Outdated Library Scanner
Detects vulnerable or end-of-life versions of jQuery, AngularJS and Bootstrap with known XSS CVEs.
What it checks
This scanner identifies the versions of common front-end libraries like jQuery, AngularJS and Bootstrap that your site loads. It flags those that are vulnerable or end-of-life versions with known, documented XSS flaws.
Why it matters
Running a library with public vulnerabilities is a well-known open door: attackers look for exactly those versions because the flaw is already published. An XSS through an outdated library can allow session theft or content injection on your site.
How to fix it
Update those libraries to a supported version with no known vulnerabilities, checking first that nothing breaks. If a library is no longer maintained, like AngularJS, consider migrating to a modern alternative that still gets updates.
