Significant security enhancements

Because certain vulnerabilities were identified that can be used to access customer data, the new release brings 33 enhancements that help close remote code execution (RCE) and cross-site scripting (XSS) weaknesses.

These include a new Composer plugin that helps prevent dependency confusion and identifies malicious packages with the same names as internal packages on the public package repository. 

Rate limiting, a feature that imposes restrictions on the size or number of resources that can be requested by a user, is now built-in to Magento APIs.

ReCaptcha coverage has been extended to include web APIs that have corresponding HTML pages and also the Place Order storefront page and payment-related web APIs. This extended coverage adds an anti-brute force mechanism to protect stores from carding attacks.

One thing to note is that merchants who are interested in installing only the time-sensitive security patches and skip the other features, can do so by installing Patch 2.4.2-p2, a security-only patch that provides fixes for vulnerabilities that have been identified in the Magento 2.4.2 release.

However, installing the security-only patches will provide security bug fixes only, not the additional security enhancements that are included in the full release, like the aforementioned rate-limiting and the extended reCaptcha coverage.

A better performing eCommerce platform

The new release will bring us a platform that comes packed with enhanced features which will help merchants tackle all complexities of modern eCommerce.

The new feature from PayPal, PayPal Pay Later allows shoppers to choose the option of short-term, interest-free payments and other special financing options that they can use to buy the product and pay later while merchants get paid up front.

The new Adobe Commerce 2.4.3 is steadily stepping towards taking full advantage of Artificial Intelligence. The Live Search function, which combines the power of Adobe Sensei and commerce data submitted by merchants, will help shoppers get more relevant search results, thus creating a more personalized shopping experience. At the same time, Live Search will act as a reporting tool which in turn will help merchants understand what products are preferred by their customers and push them on their stores.

Creating high quality content is now easier than ever thanks to the seamless integration with Adobe Stock, which provides access to millions of photos, vectors and other media assets. Adobe Stock can now be configured to be available in the Magento Admin workspace.

For those who want to create high quality app-like shopping experiences via mobile and desktop devices, this new version works seamlessly with the latest version of PWA Studio and Venia.
