Adobe Commerce CVE-2026-71362 is a critical remote code execution vulnerability affecting Adobe Commerce and Magento Open Source platforms. Disclosed in August 2026, this vulnerability allows attackers to execute arbitrary code on affected systems without authentication, potentially leading to complete compromise of the e-commerce infrastructure.

What Is CVE-2026-71362?

CVE-2026-71362 impacts Adobe Commerce versions prior to 2.4.7-p3 and Magento Open Source versions prior to 2.4.7-p3. The vulnerability stems from improper input validation in the product's REST API endpoint, allowing malicious actors to send crafted requests that bypass authentication checks and execute system commands.

Attack Vector and Impact

The attack vector exploits the Adobe Commerce REST API, specifically endpoints handling customer authentication and session management. Attackers can send specially crafted HTTP requests that trigger insecure deserialization, resulting in remote code execution with the privileges of the web server user.

Who is affected:

• Adobe Commerce merchants running versions 2.4.6 and earlier
• Magento Open Source stores running versions 2.4.6 and earlier
• Any integrated third-party extensions that interact with the vulnerable API endpoints

Technical Details

Security researchers have observed active exploitation of CVE-2026-71362 in the wild shortly after public disclosure. The vulnerability has a CVSS score of 9.8 (Critical), classifying it as a zero-day severity flaw. The exploit allows attackers to:

• Execute arbitrary code on the server
• Access sensitive customer data including payment information
• Modify e-commerce transactions
• Deploy malware or ransomware on compromised systems
• Use compromised servers as pivot points for further network attacks

Mitigation and Patching

Immediate actions:

1. Update immediately: Upgrade Adobe Commerce to version 2.4.7-p3 or later, or Magento Open Source to 2.4.7-p3 or later. These patches contain the fix for CVE-2026-71362.

2. Disable vulnerable REST endpoints: If immediate patching is not possible, consider temporarily disabling the affected REST API endpoints until the update can be applied.

3. Network segmentation: Isolate Adobe Commerce servers from public-facing networks where possible.

4. Monitor logs: Review web server access logs and Adobe Commerce logs for suspicious API activity, particularly POST requests to the customer authentication endpoints.

Long-term recommendations:

• Implement web application firewall (WAF) rules to block exploitation attempts
• Regularly audit REST API endpoints for security misconfigurations
• Keep all Adobe Commerce extensions and integrations up to date
• Conduct regular security assessments of e-commerce infrastructure

Detection

Organizations can detect potential exploitation attempts by monitoring for:

• Unusual POST requests to /rest/V1/integration/customer/token endpoint
• Failed authentication attempts followed by successful session creation
• Unusual API call patterns from unfamiliar IP addresses
• Unexpected system command execution in web server logs
• Unexplained changes to e-commerce order data or customer information

Frequently Asked Questions

Q: Can I still use my Adobe Commerce store while waiting for the patch? A: It is strongly recommended to apply the patch as soon as possible. If you must continue operating, implement the mitigation steps above and closely monitor your system logs for suspicious activity.

Q: How do I check my current Adobe Commerce version? A: Navigate to Admin > System > Web Setup Wizard > System > Check for system updates, or check the version number in the composer.json file of your Adobe Commerce installation.

Q: Will the patch break my custom extensions? The 2.4.7-p3 update is designed to be backward compatible. However, as with any major update, test the patch in a staging environment before applying it to production.

Q: Is Magento Cloud affected by CVE-2026-71362? Magento Cloud customers should contact Magento Commerce support for specific patch guidance, as cloud environments may have additional deployment considerations.

Q: What data is at risk if my system is exploited? Customer data including names, addresses, phone numbers, and potentially payment card information could be accessed by attackers exploiting this vulnerability.

Q: Are Magento Open Source stores also at risk? Yes, Magento Open Source versions prior to 2.4.7-p3 are affected by the same vulnerability.

Q: How quickly should I apply this patch? Given the critical CVSS 9.8 rating and active exploitation in the wild, apply the patch as soon as your maintenance window allows, ideally within 24-48 hours.
