Adobe Commerce and Magento REST API Account Takeover (CVE-2025-54236)

Historical catalog analysis: CISA added this entry on October 24, 2025. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.

What the vulnerability is

CVE-2025-54236 is an improper input validation vulnerability (CWE-20) affecting Adobe Commerce and Magento Open Source. The flaw exists within the Commerce REST API, where a failure to properly validate input could allow an unauthorized actor to take over customer accounts.

Exposure and applicability

This vulnerability applies to organizations deploying Adobe Commerce or Magento Open Source environments that expose the Commerce REST API. Because this vector targets customer account access, exposure is highest for e-commerce platforms with large customer bases and public-facing API endpoints. The inclusion of this CVE in CISA’s Known Exploited Vulnerabilities (KEV) catalog as of October 24, 2025, indicates that the vulnerability has been observed in active exploitation.

Remediation priorities

Based on the KEV status and the potential for account takeover, remediation should be prioritized as a critical path. Our analysis suggests the following priority sequence:

1. Immediate Patching: Apply vendor-supplied mitigations according to Adobe’s official instructions. This is the primary method for closing the input validation gap.
2. Cloud Configuration Review: For organizations utilizing cloud services, review configurations in alignment with BOD 22-01 guidance to ensure that the environment is not inadvertently exposing vulnerable API versions.
3. Service Decommissioning: In scenarios where mitigations cannot be applied or are unavailable for a specific legacy version, the product should be discontinued to eliminate the attack surface.

How to validate remediation

Verification must move beyond simple version checks, as a deployed patch does not always guarantee that the vulnerability is neutralized in a customized environment. To verify that exposure has been reduced, defenders should:

• Confirm Patch Application: Verify that the specific security update addressing CVE-2025-54236 is active across all production and staging nodes.
• API Endpoint Testing: In a non-production environment, validate that the Commerce REST API no longer accepts the malformed inputs associated with this improper validation flaw.
• Configuration Audit: Ensure that any compensating controls or WAF rules intended to block exploit attempts are actively logging and dropping traffic targeting the affected API endpoints.

Limits and open questions

While patching addresses the root cause, residual risk remains if attackers have already leveraged this vulnerability to compromise accounts prior to remediation. Patching prevents new takeovers but does not automatically revert unauthorized changes made to customer accounts during the window of exposure. It remains unknown whether this vulnerability has been utilized by known ransomware campaigns.
