Key Updates in Magento 2.4.8-P3

This release includes the following highlights:

• Fix for CVE-2025-54236 to resolve a REST API vulnerability.
• Updated parameters for REST API security compliance.
• Fix for ACP2E-3874: issue related to order details.
• Fix for AC-15446: issue related to email messaging.
• Migrate from TinyMCE to Hugerte.org.
• Added support for Apache ActiveMQ Artemis STOMP protocol.

We’ll go through each update and fix in a way that’s easy to digest, particularly for someone who isn’t a developer. That way, you can be sure you’re keeping your webstore safe, functional, and secure.

Fix for CVE-2025-54236

Adobe had some reports of vulnerabilities in which an attacker could potentially take over customer accounts through the Commerce REST API. While Adobe did not report real cases or evidence that malicious actors had exploited this vulnerability, they released a hotfix to patch the vulnerability in September of 2025.

If you applied this patch (APSB25-88) then you are already in the clear, but 2.4.8 p3 has this fix built-in, so no additional steps are required.

REST API Constructor Parameter Validation

The Adobe Commerce REST API is a tool that can be leveraged by developers to create apps and integrations with external tools such as CRMs or content management systems. Given the recent security changes, we strongly urge developers to review REST API constructor parameter validation and update their extensions for compliance.

Store owners and web managers should update their modules to the latest available versions to ensure their webstores remain secure. Otherwise, no further action is required.

Fix for ACP2E-3874

Adobe reported an issue with order details in which the incorrect values would show for the row totals attributes for cases where several of the same item were ordered. This issue is resolved in 2.4.8-p3.

Fix for AC-15446

Adobe Commerce 2.4.8-p2 Security Release introduced a bug in the Magento framework for email communication where the call for body text wasn’t completed correctly. This issue is resolved in 2.4.8-p3.

Migrate from TinyMCE to HugeRTE.org

The TinyMCE core editor previously powered the Magento page builder for content pages or blocks on your website. This builder gave store owners an easy-to-use content management WYSIWYG (what you see is what you get) editor, allowing them to simply drag and drop elements with no need for coding experience.

Due to some licensing incompatibilities and known vulnerabilities, Adobe Commerce has migrated to HugeRTE editor.

From the user perspective, not much will change, but there’s now a different engine powering the page builder with this latest release.

Added Support for Apache ActiveMQ Artemis STOMP Protocol

The 2.4.8-p3 release includes support for the Apache ActiveMQ Artemis STOMP protocol, which provides additional tools for developers around automated messaging (Message Queues Overview | Adobe Commerce).

For a store owner or web manager, this isn’t something you have to worry about. This update mostly affects developers.

Future Roadmap: What Future Security Releases Are Coming from Adobe?

The next patch release of 2.4.8-p4 is set to release on March 10, 2026. Meanwhile, Adobe continues working on beta releases for 2.4.9 during the first quarter of 2026. The official launch of Adobe Commerce 2.4.9 is scheduled for a May 12, 2026, release.

In the meantime, we recommend keeping an eye out for any security patches or hotfixes to keep your webstore as secure as possible.
