How Can You Immediately Protect Your Magento Store from This Critical Security Flaw?
A serious security weakness, known as CVE-2025-54236, affects Adobe Commerce and Magento websites. This flaw is critical because it allows an attacker to act without needing to log in. They can upload harmful files to your server. This access could let them take full control of your e-commerce store.
Security experts have rated this vulnerability with a score of 9.1 out of 10. A score this high means the risk is severe. Prompt action is necessary to protect your business and customer data.
Key Details
- Affected Software: Adobe Commerce (formerly Magento).
- The Threat: An unauthenticated attacker can upload files and potentially take over your system. This is a form of remote code execution (RCE).
- Scope of Impact: Magento powers over 130,000 websites online. Many of these sites could be at risk.
- Adobe Commerce Solution: Users of Adobe’s enterprise cloud solution should already be protected, as Adobe patches these systems automatically. If you manage your own Magento installation, you must apply security updates yourself.
This vulnerability involves a problem with nested deserialization. This process is how the software handles and processes data. The flaw allows an attacker to send specially crafted data that the system will mishandle, creating a security hole. You should check for official patches from Adobe and apply them immediately to any self-hosted Magento installations.
