How to fix info disclosure x powered by on Shopify

Steps for Shopify

1. Shopify's infrastructure manages all server-level response headers; store owners cannot directly modify X-Powered-By headers.
2. Shopify does not expose an X-Powered-By header by default on its standard storefronts — if a scanner flagged one, it likely originated from a third-party app proxy or a custom Hydrogen/headless deployment.
3. For Hydrogen (headless) deployments on Oxygen: open your Hydrogen app's server entry file (e.g. server.ts), find the Response object, and explicitly delete the header: response.headers.delete('X-Powered-By');
4. For third-party app embeds adding the header, contact that app's support to request they suppress it on their proxy responses.

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.
