---

Description

Magento 2.4-develop

Current Content Security Policy setup doesn't allow to load images and fonts via data: scheme which is quite a popular method to load local resources (base64 encoded images). Additionally, it's used internally by the browser cache (Chrome) when you refresh the page.

Manual testing scenarios (*)

1. Add Base64 image or font to Home page
2. Open Luma homepage and open browser console.
3. Refresh the page to trigger resource loading from the browser cache.
4. Inspect errors in the console:

5. Apply the patch, and try again. No errors should appear in the log.
