How to fix info disclosure server on Wix

Steps for Wix

1. Wix is a fully hosted platform — you have no access to the underlying web server configuration, and Wix manages all response headers at the infrastructure level.
2. Wix does not expose detailed server version strings to end users by design.
3. If your Wix site uses a custom domain proxied through Cloudflare (Wix does not officially support full Cloudflare proxying, but some setups use it): apply a Transform Rule in Cloudflare to remove the `Server` header as described in the Cloudflare steps above.
4. If a scanner flags a `Server` header on a Wix site, contact Wix Support — merchants cannot resolve this independently.

## Apache (.htaccess or httpd.conf)
ServerTokens Prod
ServerSignature Off
Header unset Server

## nginx (nginx.conf — inside http{} or server{} block)
server_tokens off;

## IIS (web.config — inside <system.webServer>)
<security>
  <requestFiltering removeServerHeader="true" />
</security>

## Cloudflare Transform Rule (via dashboard UI)
# Rules → Transform Rules → Modify Response Header
# Operation: Remove
# Header name: server

What is info disclosure server?

Every time a browser (or a hacker's scanner) requests a page from your store, your web server sends back a response that often includes a `Server` header — a small piece of text that announces exactly what software is running, right down to the version number (e.g., `Microsoft-IIS/10.0`, `Apache/2.4.51`, or `nginx/1.18.0`). This is called information disclosure. Removing or blanking that header is a simple configuration change that stops your store from broadcasting its technology stack to anyone who looks.

Attackers routinely scan millions of sites looking for specific server versions with known security vulnerabilities — your `Server` header is a free map that tells them exactly which exploits to try. Exposing it significantly lowers the effort required to target your store, putting customer data, payment information, and your reputation at risk. OWASP lists this pattern under A05:2021 Security Misconfiguration, one of the most common causes of real-world breaches. Removing the header doesn't fix every vulnerability, but it removes the signpost that guides attackers to them, and it is expected by PCI DSS compliance auditors.
