Outdated JavaScript libraries (Security)
Known old majors (jQuery 1/2, AngularJS 1, Bootstrap 3, …) often have public CVEs.
Pass condition in our engine: No known outdated library versions detected in script URLs.
This Security check is part of SEO-GEO scoring 2.2.1, last updated 2026-09-18. About 90 percent of the evaluation runs on the HTML we crawl, so you can verify the same pass condition with a free report.
1. Problem description
We parse library names and majors from script URLs. This is not a full SCA (Software Composition Analysis) scan — it will miss bundled copies with hashed names. Treat hits as a patching prompt.
2. Most common causes
- A theme from 2017 still loading jquery-1.12.4.min.js.
- A plugin ships Moment 2.x forever.
3. How to fix it
- Upgrade to a supported major.
- Remove unused libraries.
- Run npm audit / a real SCA tool on your build.
Test this check
We fetch only this URL (plus robots.txt / llms.txt at the domain root when the check needs them). We do not crawl the rest of the site like a full report.
