CVE-2025-54267: Adobe Commerce Auth Bypass Vulnerability

CVE-2025-54267 Overview

CVE-2025-54267 is an Incorrect Authorization vulnerability [CWE-863] affecting Adobe Commerce, Adobe Commerce B2B, and Magento Open Source. The flaw allows a low-privileged authenticated attacker to bypass server-side authorization checks and perform actions reserved for higher-privileged users. Exploitation occurs over the network and requires no user interaction. Successful attacks affect data integrity by enabling unauthorized modifications, though confidentiality and availability remain unaffected. Adobe published fixes in security bulletin APSB25-94 on October 14, 2025. Affected releases include Adobe Commerce 2.4.9-alpha2, 2.4.8-p2, 2.4.7-p7, 2.4.6-p12, 2.4.5-p14, 2.4.4-p15, and earlier, plus corresponding Adobe Commerce B2B and Magento Open Source branches.

Critical Impact
An authenticated low-privileged user can elevate permissions to modify data reserved for higher-privileged roles, undermining the integrity of storefront and administrative operations.

Affected Products

Adobe Commerce 2.4.4 through 2.4.9-alpha2 and all listed patch releases
Adobe Commerce B2B versions 1.3.3 through 1.5.3-alpha2
Magento Open Source 2.4.6 through 2.4.9-alpha2

Technical Details for CVE-2025-54267

Vulnerability Analysis

CVE-2025-54267 is classified under [CWE-863], Incorrect Authorization. Adobe Commerce enforces role-based access control across its REST, GraphQL, and admin backend interfaces. In the affected releases, at least one server-side authorization check fails to correctly validate the acting user's assigned scope or role. As a result, an attacker holding valid low-privileged credentials can invoke functionality that should be restricted to accounts with elevated permissions.

The impact is limited to integrity. An attacker cannot read confidential data or crash the service through this specific flaw, but can alter records, configurations, or transactional data that they should not be authorized to modify. In an e-commerce context, this can translate to tampering with catalog items, pricing, order state, or customer records, depending on the underlying endpoint.

Root Cause

The root cause is a missing or incomplete authorization enforcement path within Adobe Commerce request handling. The application appears to authenticate the request but does not consistently verify that the caller's role permits the requested action. Adobe has not published exploit-level detail, and the fix is delivered as part of the vendor patch release documented in APSB25-94.

Attack Vector

The attack vector is network-based and requires an authenticated session with low privileges, such as a standard customer, B2B buyer, or limited backend account. No user interaction is required. An attacker sends a crafted HTTP request to a vulnerable endpoint, using their existing session or API token. The server processes the request without applying the correct authorization decision, allowing the privileged action to succeed. Because no verified proof-of-concept has been published, defenders should treat any anomalous state-changing request from a low-privileged account as suspect on unpatched systems. Refer to the Adobe Security Advisory APSB25-94 for vendor guidance.

Detection Methods for CVE-2025-54267

Indicators of Compromise

Unexpected state changes to catalog, pricing, order, or customer records attributed to non-administrative accounts.
API or GraphQL calls from low-privileged tokens targeting mutation endpoints normally restricted to admin or elevated roles.
Sudden spikes in authenticated POST, PUT, or DELETE requests originating from a single low-privileged customer or B2B account.
Audit log entries showing successful privileged operations without a corresponding admin login.

Detection Strategies

Baseline the set of endpoints each user role is expected to call, then alert when low-privileged accounts invoke administrative routes.
Correlate web server access logs with Magento admin action logs to identify successful state changes that lack matching admin authentication.
Review historical logs going back to the earliest affected release date for anomalous privileged actions by non-admin users.

Monitoring Recommendations

Forward Adobe Commerce web server, application, and admin audit logs into a centralized analytics platform for correlation and long-term retention.
Monitor administrative configuration tables and price/catalog datasets for unauthorized modifications and enable change alerts.
Track authentication events for low-privileged accounts that suddenly perform high-value operations, and require re-authentication for sensitive actions.

How to Mitigate CVE-2025-54267

Immediate Actions Required

Apply the Adobe Commerce, Adobe Commerce B2B, and Magento Open Source updates listed in Adobe Security Advisory APSB25-94 as the primary remediation.
Inventory all Adobe Commerce, Commerce B2B, and Magento Open Source deployments and confirm each is on a fixed release beyond 2.4.9-alpha2, 2.4.8-p2, 2.4.7-p7, 2.4.6-p12, 2.4.5-p14, or 2.4.4-p15.
Review recent audit logs for privileged actions performed by low-privileged accounts and roll back unauthorized changes.
Rotate API tokens and credentials for any account suspected of misuse.

Patch Information

Adobe addressed CVE-2025-54267 in the patch release documented in APSB25-94. Administrators should upgrade to the vendor-supplied patched versions for each affected branch. Refer to the Adobe Security Advisory APSB25-94 for the exact fixed builds and download instructions.

Workarounds

Restrict access to administrative and API endpoints behind a web application firewall, and tighten allow-lists for privileged routes until patching is complete.
Enforce the principle of least privilege by auditing customer, B2B, and staff accounts and removing unused or over-privileged roles.
Require multi-factor authentication on all backend and API accounts to raise the cost of credential-based abuse.
