Key points
- The flaw is rated Critical with a CVSS score of 9.8.
- Exploitation requires no user interaction or authentication.
- Multiple versions of Commerce and Magento Open Source are affected.
Adobe Commerce and Magento Open Source contain a severe authorization flaw that permits remote code execution. According to the National Vulnerability Database, this vulnerability, identified as CVE-2026-92909, allows attackers to run arbitrary code in the context of the current user. The issue stems from incorrect authorization checks within the software.
By the numbers
- CVSS 9.8: The severity rating assigned to CVE-2026-92909.
- CWE-863: The common weakness enumeration for incorrect authorization.
- Zero interaction: The number of user actions required for exploitation.
What the figures mean
The CVSS score of 9.8 indicates a critical risk level for any organization running the affected software. Because the flaw involves incorrect authorization, attackers can bypass security controls to execute code remotely. The National Vulnerability Database notes that exploitation does not require user interaction, meaning automated attacks are possible. This zero-click nature significantly increases the attack surface for managed service providers and their clients.
What should you do?
Managed service providers must immediately inventory all client environments running Adobe Commerce or Magento Open Source. Identify which specific versions are deployed, as multiple releases are affected. Prioritize systems exposed to the internet for immediate assessment. Coordinate with development teams to verify if custom code interacts with the vulnerable authorization mechanisms.
Operational impact
Teams usually begin by mapping all instances of the affected software across client accounts. Check whether any internal suppliers or partners host these platforms on shared infrastructure. Notify the security operations center and client success managers about the potential exposure. Determine if any recent deployments used the vulnerable versions. Ensure that incident response plans account for remote code execution scenarios.
Background: Incident response plans
Incident response plans fail when teams assume they cover every attack vector or treat them as static documents. You must focus on decision trees, not scripts. Plan for communication breakdowns, not just technical fixes. Regular table-top exercises reveal gaps that documentation hides.

What to do and how to stay safe: Adobe Commerce
- Audit all managed environments to identify installations of Adobe Commerce or Magento Open Source at or below the affected versions.
- Monitor server logs for unusual process executions or unauthorized code activity that may indicate exploitation attempts.
- Restrict network access to affected systems to limit exposure until a vendor update is available and tested.
- Communicate the risk to clients, emphasizing that no user interaction is required for an attacker to exploit this flaw.
