There are many enhancements and improvements in the performance and security of the new release of Adobe Commerce. Adobe Commerce 2.4.3 includes expansion of reCAPTCHA coverage and inclusion of built-in rate limiting. Core composer dependencies and 3rd party libraries have also been upgraded to the latest versions, compatible with newer PHP 8.

There are 370+ fixes in the core code, along with 33 security enhancements. All known issues of the previous release have also been fixed in this release.

Other Release Information

Although code for these features is bundled with the quarterly release of the Magento core code, for other projects such as Page Builder, PWA Studio releases independently. Issues of these projects are documented in the separate, project-specific release information.


Let’s go through the major highlights in this release:

Substantial Security Enhancements

In this release, there are 33 security fixes along with platform security improvements. These security fixes have been backported to Magento 2.4.2-p2 and Magento 2.3.7-p1.

These security improvements will close RCE (Remote Code Execution) and XX (Cross-site Scripting) vulnerabilities.

Other Security Enhancements

Security improvements also include compliance with the latest security best practices, such as:

  • A new Composer plugin has been added to prevent dependency confusion and identify malicious packages with the same name as internal packages on the public package repository.
  • Magento APIs now have Rate limiting features for preventing denial-of-service (DoS) attacks. There is also the ability to impose restrictions on the size of resources of Web APIs. The default value is 20.

ReCAPTCHA abilities have been expanded to include

  • Web APIs with HTML pages are covered with ReCAPTCHA, excluding the web APIs accessible through integrations. ReCAPTCHA protects your Magento store from spam attacks. When the Web APIs are accessed through 3rd party integrations that use OAuth, ReCAPTCHA gets disabled.
  • Payment-related web APIs and Place Order storefront page. ReCAPTCHA protection for these pages is disabled by default and can be enabled through Admin.
