How to fix info disclosure x powered by on Wix

Steps for Wix

1. Wix is a fully hosted platform; server response headers are controlled by Wix infrastructure and cannot be modified by store owners through the standard editor.
2. Wix does not expose X-Powered-By headers on standard storefronts.
3. If you are using Wix Headless (Wix's headless commerce offering) with a custom server, suppress the header in your server middleware as shown in the Node.js/Express code snippet below.
4. If a scanner flagged this on your Wix site, it may have originated from an embedded third-party widget or script — contact that vendor to request they suppress the header on their end.

What is info disclosure x powered by?

Every time a browser (or a hacker's scanner) requests a page from your store, your web server sends back a set of invisible "response headers" alongside the visible page content. One of these, called X-Powered-By, often reveals exactly what software is running behind the scenes — for example "WP Engine", "PHP/8.1.12", or "Express". This header is not required for your site to work; it exists purely as a default that most web frameworks and hosting platforms add automatically. You can safely remove it or replace it with a meaningless placeholder.

Exposing your technology stack is a gift to attackers. When a scanner sees "WP Engine" or "PHP/8.1.2" in the X-Powered-By header, it immediately knows which known vulnerabilities to try — dramatically lowering the effort needed to compromise your store, steal customer data, or inject malware. This falls squarely under OWASP A05:2021 Security Misconfiguration, one of the most common causes of real-world breaches. Beyond security, a breach that exposes customer payment or personal data creates legal liability under GDPR, CCPA, and PCI-DSS. Removing this header takes minutes and eliminates one of the easiest reconnaissance signals you hand to bad actors for free.
