Adobe Commerce and Magento Open Source are affected by a critical file upload vulnerability that could lead to arbitrary code execution via user interaction.

This is an unrestricted file upload vulnerability (CWE-434) that allows an attacker to upload dangerous file types. While exploitation requires a victim to interact with a crafted URL, successful execution allows for full code execution in the context of the user.

The ability to upload malicious files can result in complete site compromise and unauthorized access to customer sessions or sensitive data. Given the critical CVSS score of 9.6, this vulnerability represents a major risk to e-commerce operations and customer data integrity.

Immediate Action: Update Adobe Commerce, Magento Open Source, and associated plugins to the July 2026 security release versions as specified in the vendor advisory.

Proactive Monitoring: Monitor file upload directories for unauthorized scripts or unexpected changes in file permissions.

Compensating Controls: Implement file type validation and restrict execution permissions in directories where user-uploaded content is stored.

Public Exploit Available: No

Security teams should prioritize patching these components immediately. In addition to patching, reinforce user awareness regarding the risks associated with interacting with untrusted links or external web content.
