How to fix vulnerable component jquery on Wix

Steps for Wix

1. Wix manages jQuery internally as part of its platform — you cannot directly upgrade the version Wix core uses. Ensure your Wix site is always on the latest published version (Wix updates this automatically).
2. If you have added custom HTML via Wix Editor → Add → Embed → Custom Code or HTML iFrame widgets that include a manual jQuery <script> tag, click that element → Settings and update the CDN URL to 'https://code.jquery.com/jquery-3.7.1.min.js'.
3. Go to Wix Dashboard → Settings → Custom Code (under Advanced) and review any code snippets injected in the Head or Body — update any jQuery URLs found there.
4. For Wix Apps you have installed, contact the app developer if their widget loads an outdated jQuery; Wix App Market apps are the developer's responsibility to patch.
5. After saving, use DevTools → Network on your live site to verify no outdated jQuery version is loaded by your custom code.

What is vulnerable component jquery?

jQuery is a JavaScript library that most websites load to make interactive features easier to build. Like any software, older versions of jQuery contain security bugs that have been discovered and publicly documented — these are called CVEs (Common Vulnerabilities and Exposures). When your store loads an outdated jQuery version, it is shipping known security holes directly to every visitor's browser. The fix is simply to replace the old file with a current, patched version.

Outdated jQuery versions (especially anything below 3.5.0) contain confirmed XSS vulnerabilities that allow attackers to inject malicious scripts into your pages — stealing customer payment data, session cookies, or redirecting shoppers to phishing sites. This directly endangers customer trust, can result in PCI-DSS compliance failures, and may expose you to legal liability under GDPR or CCPA if customer data is compromised. Google's Safe Browsing also flags sites that serve known malicious scripts, which can trigger browser security warnings that wipe out organic traffic overnight. OWASP lists Vulnerable and Outdated Components as #6 in its Top Ten most critical web application security risks precisely because these attacks are automated, common, and easy for criminals to run at scale.
