Highlights of Magento 2.4 vs 2.3

1. Magento 2.4 vs 2.3: Stronger Security

  • Magento 2.4 version provides 30+ fixes over security issues to protect the account against remote code execution (RCE) and cross-site scripting (XSS).
  • Access to Magento Admin UI now requires Two-factor authentication (2FA) from all devices.

Others security improvements worth noting:

  • Template filter strict mode is now enabled by default. The Magento team must have realized the security flaws of template filters in legacy mode. Changing the default setting to strict mode is expected to stop any attempts to remote code execution (RCE).

  • A new \Magento\Framework\Escaper class is now available. Both .phtml templates and the PHP classes responsible for generating HTML are now provided with the new class.  
  • New security.txt file. Magento 2.4 also supports a new security.txt file. It is known as an industry-standard file on the server that collects reports on security issues from researchers to sites admins.
