All the known issues found in Magento version 2.4.2 have been fixed in this release. Additionally, 33 security fixes or improvements have been made to close Remote Code Execution (RCE) and cross-site scripting (XSS) vulnerabilities.

In case you cannot upgrade to the latest version immediately, it is recommended to at least install one of the security patch versions:

  1. Adobe Commerce 2.4.2-p2
  2. Adobe Commerce 2.3.7-p1

The Adobe commerce 2.4.2-p2 release fixes all the vulnerabilities found in 2.4.2.

reCAPTCHA expansion

With the expansion of reCAPTCHA, your sites are much more secure from spam and bots. This protects stores from carding attacks through brute force mechanisms. reCAPTCHA will be disabled as default for the Place Order storefront page and payment-related web APIs. This can be enabled from the Admin panel.

Built-in rate limiting

Rate limiting is now inbuilt with Magento. Now you can limit network traffic by capping the repeat actions within a time frame. This reduces malicious bot activity and protects your site from DDoS attacks.

New composer plugin

With the Magento 2.4.3 release, Adobe is including a new composer plugin that performs integrity checks during installation to reduce the vulnerability known as dependency confusion.

Adobe and extension developers use private and public composer package repositories to deliver code for updates or fixes to Adobe Commerce and Magento Open Source merchants.

The private composer package repository at is audited by Adobe for malware and package upload validation. But an unused namespace at the public repository at can be used to upload malicious packages, which in turn can be passed on to the merchant’s Commerce instances. To avoid dependency confusion it is best to

  • Use the plugin while testing any extension’s installation flow
  • Verify that the namespace on is owned by you

Infrastructure updates

The release enhances the following functional areas and the quality of the framework

  • Customer Account
  • Catalog
  • CMS

PayPal Pay Later support

Platform Enhancements

Magento 2.4.3 is not compatible with PHP 8.x yet, but the platform updates will take it one step further to reaching that goal. With this in mind, the Core Composer dependencies and third-party libraries will be upgraded to make it compatible with PHP 8.x.
