Arbitrary Code Execution in Adobe Commerce and Magento Open Source (CVE-2026-75650)

Catalog analysis: CISA added this entry on September 08, 2026. The entry reflects catalog information retrieved on September 08, 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-2026-75650 is a vulnerability involving the improper neutralization of special elements used in a template engine (CWE-1336). This flaw affects Adobe Commerce and Magento Open Source, potentially allowing an attacker to execute arbitrary code on the underlying system.

Exposure and applicability

This vulnerability applies to organizations deploying Adobe Commerce or Magento Open Source. The risk is most acute for assets with direct internet exposure, as these provide a more accessible path for potential exploitation of the template engine flaw. Infrastructure owners should prioritize identifying all instances of these platforms across their environment to determine the total attack surface.

Remediation priorities

Based on our analysis, defenders should prioritize the following actions:

1. Apply Vendor Mitigations: Immediate priority should be given to implementing the corrective actions specified in Adobe’s security instructions. This is the primary method for reducing the vulnerability’s exploitability.
2. Conduct Forensic Triage: Because this vulnerability has been added to CISA’s Known Exploited Vulnerabilities catalog and specifically requires forensic triage, organizations should not assume that patching alone is sufficient. A review of system logs and integrity checks is necessary to determine if the vulnerability was exploited prior to remediation.
3. Evaluate Internet Exposure: Assets that are internet-facing should be patched first, as they represent a higher risk profile than internal-only instances.

How to validate remediation

Verification must go beyond confirming a version number or the presence of a patch. To ensure exposure is actually reduced, defenders should:

• Verify Mitigation Deployment: Confirm that vendor-supplied mitigations are active and correctly configured across all affected nodes.
• Perform Post-Patch Triage: Execute the forensic triage requirements to confirm no indicators of compromise exist that would render the patch ineffective (e.g., existing web shells).
• Validate Configuration: Ensure that template engine configurations align with current security hardening guidelines provided by the vendor.

Limits and open questions

Applying a patch or mitigation could reduce the likelihood of exploitation, but it does not guarantee absolute prevention if other systemic weaknesses exist. It remains unknown whether this vulnerability is being utilized in known ransomware campaigns. Furthermore, while CISA has established a deadline for federal agencies, non-federal organizations must determine their own risk-based timelines based on their specific exposure and business criticality.
