How to fix missing permissions policy on Magento Open Source

Steps for Magento Open Source

1. For Apache: add to .htaccess in Magento root: `Header always set Permissions-Policy "camera=(), microphone=(), geolocation=()"` (requires mod_headers).
2. For Nginx: add to your server {} block: `add_header Permissions-Policy "camera=(), microphone=(), geolocation=()" always;` and reload Nginx.
3. Alternatively, build a small custom module that adds the header via an event observer or plugin on the HTTP response object.
4. Clear caches: php bin/magento cache:flush
5. Verify via Chrome DevTools Network tab or securityheaders.com.

Permissions-Policy: camera=(), microphone=(), geolocation=(), payment=(), usb=(), fullscreen=(self)

What is missing permissions policy?

The Permissions-Policy header (formerly called Feature-Policy) is a security instruction your web server sends to every visitor's browser. It acts like a bouncer's list for powerful browser features — it tells the browser exactly which features your site is allowed to use, and blocks everything else. For example, you can declare that your store never needs access to a visitor's camera, microphone, or precise location, so even if malicious code was somehow injected into your page, the browser would refuse to grant that access. Without this header, browsers apply loose default rules, leaving those features potentially available to any script running on your pages.

Missing this header is flagged under OWASP A05:2021 (Security Misconfiguration) — one of the most common vulnerability categories found on real sites. If third-party scripts (ad networks, chat widgets, analytics) or injected malicious code try to silently access a shopper's camera, microphone, or location, nothing at the browser level stops them without this header. For an ecommerce store, that is a direct privacy and trust risk: a single reported incident of covert data capture can destroy customer confidence and trigger GDPR/CCPA regulatory scrutiny. Adding this header is a low-effort, high-signal security hardening step that security auditors and increasingly Google's ranking systems look for as a mark of a trustworthy site.
