CVE-2026-71362: Authorization Bypass in Adobe Commerce and Magento

Catalog analysis: CISA added this entry on September 24, 2026. The entry reflects catalog information retrieved on September 25, 2026, not a snapshot archived on the inclusion date. This site’s publication date is shown separately. Check current vendor guidance before acting.

What the vulnerability is

CVE-2026-71362 is an incorrect authorization vulnerability (CWE-863) affecting Adobe Commerce and Magento. The flaw allows an attacker to gain elevated access to sensitive resources without requiring any user interaction. Because this vulnerability enables unauthorized privilege escalation, it has been added to CISA’s Known Exploited Vulnerabilities (KEV) catalog.

Exposure and applicability

This vulnerability applies to organizations deploying Adobe Commerce or Magento. The primary exposure path is the lack of proper authorization checks on sensitive resources, which could be leveraged by an attacker to bypass intended access controls. Infrastructure owners should prioritize assets that are internet-facing, as these represent the highest immediate risk for unauthorized resource access.

Remediation priorities

Our analysis suggests prioritizing remediation based on asset exposure and the following sequence:

1. Immediate Patching: Apply the mitigations provided in the vendor’s security advisory (apsb26-92.html). This is the primary method for reducing the vulnerability’s exploitability.
2. Forensic Triage: Because CISA has flagged this CVE for forensic triage, defenders should examine logs and system state for evidence of unauthorized access to sensitive resources prior to patching. This is critical because a patch prevents future exploitation but does not remove an attacker who has already gained elevated access.
3. Exposure Assessment: Identify all instances of Adobe Commerce and Magento across the environment to ensure no shadow IT or legacy installations remain unpatched.

How to validate remediation

Verification must go beyond confirming a version number or patch installation date. To assure that exposure is reduced, defenders should:

• Verify Authorization Logic: Use authorized security testing to confirm that sensitive resources previously accessible via the vulnerability now require appropriate authorization.
• Audit Access Logs: Review logs for any anomalous requests to the affected resources during the window between the vulnerability’s emergence and the application of the fix.
• Confirm Configuration: Ensure that the vendor-recommended mitigations are active and have not been overridden by custom site configurations or third-party extensions.

Limits and open questions

Applying a patch reduces the likelihood of initial compromise via this specific vector, but it does not guarantee total security. Residual risk remains if an attacker has already established persistence using the elevated access granted by CVE-2026-71362. Additionally, while CISA provides a deadline for federal agencies (September 27, 2026), non-federal organizations must determine their own urgency based on their specific threat profile and asset exposure.
