README

https://gitlab.com/sixbysix/magento2-csp-fixer

This extension provides a number of tools to help you implement a Content Security Policy (CSP) on your Magento 2 store.

Currently Magento stores may operate their CSP policies in report-only mode and remain compliant with PCI DSS. However, this is not a long-term solution and from March 2025 all Magento stores will be required to have a fully operational CSP.

Features

  • HTML Fixer
    • Converts inline event listeners to tag-based event listeners.xs
    • Converts inline styles to tag-based styles.
    • Converts inline scripts to tag-based scripts.
    • Generates nonce attributes for inline scripts and styles.
  • CSP directive management
    • Manage your CSP directives from the Magento admin panel.

  1. Add the extension to your Magento 2 store using Composer:
     composer require sixbysix/magento2-csp-fixer

 bin/magento setup:upgrade
