Adobe Commerce APSB26-146

Is your Magento or Adobe Commerce store secure?

Adobe has released APSB26-146, a critical security update for Adobe Commerce and Magento Open Source.

The update addresses CVE-2026-75650, a zero-day vulnerability that has been actively exploited in the wild.

For online businesses, this is more than a routine software update.

A vulnerable Magento store can expose critical business systems, customer information, and sensitive credentials.

🔐 What Is Adobe Commerce APSB26-146

?

APSB26-146 is Adobe’s security bulletin for a critical vulnerability affecting supported Commerce environments.

The recommended remediation includes the VULN-39341 hotfix for affected versions.

Because different Magento and Adobe Commerce versions require different remediation packages, the correct patch should be selected based on your exact installed version.

⚠️ Why Is This Security Update Urgent?

The biggest concern is confirmed exploitation.

Attackers are actively targeting vulnerable environments, which means delaying remediation increases the window in which a store may be exposed.

A compromised store could potentially impact:

• Customer and business data
• Administrator accounts
• API access
• Third-party integrations
• Payment-related systems
• Store availability and revenue

🛡️ What Should Magento Merchants Do?

First, identify the exact Adobe Commerce or Magento Open Source version running on your production environment.

Next, apply the appropriate VULN-39341 security hotfix.

After patching, don’t stop there.

Adobe recommends reviewing and rotating potentially exposed credentials and encryption keys.

Businesses should also review administrator accounts, API access, integrations, and security logs.

If the store was exposed before remediation, investigate for possible signs of compromise.

🔑 Credential Rotation Matters

Installing the security patch protects against the vulnerability going forward.

However, credentials that may have been exposed while the store was vulnerable could still present a risk.

Review and rotate relevant:

• Encryption keys
• Admin credentials
• API credentials
• Integration tokens
• Payment-related credentials
• Server and deployment credentials

🔎 Check Your Store After Patching

After applying the patch, test critical eCommerce functionality.

Verify customer login, checkout, payments, APIs, product functionality, and third-party integrations.

Also monitor server and application logs for unusual activity.

A successful deployment should leave your store both secure and fully operational.
