How to fix server version on Wix

Steps for Wix

1. Wix manages all server infrastructure; you cannot directly edit 'Server' or 'X-Powered-By' headers from the Wix dashboard.
2. If you use Wix Velo (code-based features), you can add custom response headers in a backend web module ('http-functions.js'): use 'response.headers.set()' to overwrite values, but note Wix may still inject its own headers.
3. Place a CDN or reverse proxy (e.g. Cloudflare) in front of your Wix site, then use Cloudflare Transform Rules to delete or overwrite the disclosing headers at the edge.
4. For Wix Enterprise, contact Wix support to request header suppression — they may be able to configure it at the infrastructure level.

What is server version?

Every time a browser (or a bot) requests a page from your store, your web server sends back a set of "response headers" — invisible metadata about the response. Two of these headers, `Server` and `X-Powered-By`, often broadcast exactly what software is running your site and which version it is (for example, `Server: Vercel` or `X-Powered-By: Next.js`). This is called "server version disclosure" or "technology fingerprinting." While the header itself doesn't break anything, it acts like a name-badge that tells the whole internet: "Here's exactly what I'm running."

Attackers routinely scan millions of websites looking for servers running known vulnerable versions of software. When your headers announce your exact stack, you become a much easier target — automated exploit tools can match your version against public vulnerability databases (CVEs) and launch targeted attacks in seconds, without any human involvement. Suppressing these headers is a recognised security hardening step that reduces your "attack surface" and is increasingly expected by security audits, PCI-DSS assessments, and enterprise buyers reviewing your store. It also prevents competitors or scrapers from trivially identifying and copying your technology stack. Fixing it is usually a quick-win configuration change that has zero impact on site speed or user experience.
