What is the Adobe Commerce Incorrect Authorization Vulnerability?

CVE-2026-71362 is a flaw in Adobe Commerce and Magento that allows attackers to bypass normal authorization checks. This means a user who shouldn't have access to certain features or functions could gain access and perform actions that should be restricted.

The vulnerability is related to how the software manages user permissions. If not properly configured or patched, attackers can exploit this flaw to access administrative features or otherwise restricted areas of the system.

This flaw has been added to the CISA Known Exploited Vulnerabilities (KEV) catalog, meaning it is already being used in attacks. That makes it a high-priority issue for all users of Adobe Commerce and Magento.

How Does This Affect Small and Mid-Sized Businesses?

If your business uses Adobe Commerce or Magento for e-commerce operations, you are at risk. This includes any SMBs that rely on these platforms to manage their online stores, inventory, or user access.

Attackers could exploit this vulnerability to access restricted features within the system. This could allow them to modify configurations, access admin tools, or otherwise manipulate the system in ways that disrupt or compromise your operations.

Because this vulnerability is already being exploited in the wild, there is no time to waste. Even if you haven't seen any signs of an attack, it's important to act now to prevent potential breaches.

What Should You Do This Week?

First, check if you are running an affected version of Adobe Commerce or Magento. Adobe has released a patch for this vulnerability. The federal government has given a remediation deadline of September 27, 2026.

If you're using a managed service provider or a third-party developer to maintain your site, reach out to them and request confirmation that the patch has been applied. If you're managing the system in-house, visit Adobe's security advisory page and follow their instructions for patching.

To confirm your version, run the following command in your Magento/Adobe Commerce installation directory: `php bin/magento --version`. Compare the output to Adobe's list of affected versions in their security advisory.

How Can You Tell if You've Already Been Hit?

Look for unexpected access to restricted areas of your system. For example, if non-admin users can access admin tools or modify configurations, this could be a sign of exploitation.

Check your system logs for unauthorized access attempts or unusual activity in admin areas. Look for login attempts from unknown IP addresses or unexpected changes to user permissions.

If you see any suspicious activity, isolate the affected system and contact a cybersecurity professional immediately to investigate further.
