Magento store security is more important than ever, especially with the emergence of the PHP2Shell vulnerability, which exposes vulnerable PHP environments to critical remote code execution (RCE) attacks. The PHP2Shell Magento security alert involving CVE-2026-109618 and CVE-2026-109619 highlights the risks for eCommerce businesses. Read our Critical PHP Security Alert: Protect Your Magento Store to understand the threat.
Understanding the PHP2Shell Vulnerability
PHP2Shell refers to two critical PHP security vulnerabilities that can allow unauthenticated attackers to execute malicious code on vulnerable servers. CVE-2026-109618 involves out-of-memory handling issues, while CVE-2026-109619 relates to a use-after-free memory vulnerability.
These flaws create a serious PHP remote code execution vulnerability that can affect Magento stores, potentially exposing customer information, payment-related data, and website files.
How to Fix PHP2Shell Vulnerabilities?
Follow these essential steps to strengthen your Magento store security:
1. Update Your PHP Version
The first step is applying the appropriate PHP security patch. Fixed releases include PHP 8.2.35, 8.3.36, 8.4.27, and 8.5.12. If you use an older PHP version, consult your hosting provider about verified security backports or plan an upgrade.
2. Check Magento PHP Version Compatibility
Before updating PHP, verify Magento PHP version compatibility. Different Magento and Adobe Commerce releases support different PHP versions. Check your installed Magento version, extensions, and custom modules before upgrading to avoid compatibility issues.
3. Apply Magento Security Patch Updates
Keep Magento core, extensions, and third-party modules updated. Remember that a Magento security patch update alone cannot resolve PHP2Shell because the vulnerabilities originate in the PHP runtime itself.
4. Enable Additional Security Protection
Use a Web Application Firewall (WAF), monitor suspicious requests, restrict unnecessary server access, and regularly review PHP and server logs. These additional security measures help reduce exposure but cannot replace the required PHP update.
5. Test Your Magento Store
After applying security updates, test product pages, shopping carts, checkout, payment gateways, admin functionality, and integrations. Monitor server logs to identify unusual activities or unexpected errors.
