CVE-2025-54263: Adobe Commerce Auth Bypass Vulnerability

CVE-2025-54263 Overview

CVE-2025-54263 is an Incorrect Authorization vulnerability [CWE-863] affecting Adobe Commerce, Adobe Commerce B2B, and Adobe Magento Open Source. A low-privileged authenticated attacker can leverage the flaw to bypass security controls and maintain unauthorized access to affected installations. Exploitation requires network access but no user interaction, making it suitable for automated attacks against exposed storefronts.

Adobe published the issue in security bulletin APSB25-94, covering multiple branches of the Commerce platform. The vulnerability impacts confidentiality and integrity of merchant data, customer records, and administrative resources.

Critical Impact

A low-privileged attacker with network access can bypass authorization checks in Adobe Commerce to access restricted resources and persist unauthorized access without user interaction.

Affected Products

• 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
• Adobe Commerce B2B 1.5.3-alpha2, 1.5.2-p2, 1.4.2-p7, 1.3.5-p12, 1.3.4-p14, 1.3.3-p15 and earlier
• Adobe Magento Open Source (matching 2.4.x branches)

Technical Details for CVE-2025-54263

Vulnerability Analysis

The flaw resides in Adobe Commerce authorization logic, where access decisions do not adequately validate that an authenticated principal is entitled to the requested resource or action. Because the failure occurs after authentication, any account with low privileges, such as a registered customer or limited backend user, can reach functionality that should be restricted to higher-privileged roles.

The weakness maps to CWE-863: Incorrect Authorization. The CVSS vector indicates a network-reachable issue with low attack complexity and no user interaction, scoped to confidentiality and integrity rather than availability. Successful exploitation enables attackers to maintain unauthorized access across sessions, which can support data theft, tampering with catalog or order data, and lateral movement into administrative workflows.

Root Cause

The root cause is an authorization check that evaluates whether a request is authenticated without enforcing whether the authenticated identity is authorized for the specific object or operation. This pattern often arises when role checks are applied at controller entry points but not at the data access layer, allowing crafted requests to reach protected functionality through alternate paths.

Attack Vector

An attacker creates or compromises a low-privileged account on the storefront. Using that session, the attacker issues HTTP requests against endpoints whose authorization logic is incomplete, retrieving or modifying resources owned by other tenants, customers, or administrators. No social engineering or victim interaction is needed, and the attack can be repeated to retain access. Adobe has not published exploitation details, and no public proof-of-concept code is currently available.

Detection Methods for CVE-2025-54263

Indicators of Compromise

• Unexpected access to admin or B2B endpoints from accounts that historically only used customer-facing routes.
• Creation of new administrative users, API integrations, or OAuth tokens shortly after low-privileged logins.
• Anomalous read or write operations against /rest/V1/, /graphql, or admin controllers from a single session ID.
• Modifications to order, customer, or catalog records without corresponding admin UI activity.

Detection Strategies

• Compare authenticated session role claims against the resources accessed per request and alert on mismatches.
• Hunt for HTTP 200 responses to privileged endpoints from accounts whose role should produce 401 or 403.
• Baseline normal GraphQL and REST query patterns per customer group and flag deviations.
• Review web server and application logs for repeated requests that enumerate object IDs across tenants.

Monitoring Recommendations

• Forward Adobe Commerce application, web server, and database audit logs to a centralized analytics platform for correlation.
• Monitor for privilege changes, new admin role assignments, and modifications to ACL rules.
• Track outbound data volume from the Commerce application tier to detect bulk extraction.

How to Mitigate CVE-2025-54263

Immediate Actions Required

• Apply the patched Adobe Commerce release that corresponds to your deployed branch as listed in security bulletin APSB25-94.
• Inventory all Commerce, Commerce B2B, and Magento Open Source instances, including non-production environments, and confirm version levels.
• Audit existing low-privileged accounts, disable dormant users, and rotate API keys and integration tokens.
• Review recent admin and B2B activity logs for signs of unauthorized access during the exposure window.

Patch Information

Adobe addressed CVE-2025-54263 in the security update documented in the Adobe Magento Security Advisory APSB25-94. Upgrade to the fixed releases for each supported branch, including the latest patches above 2.4.8-p2, 2.4.7-p7, 2.4.6-p12, 2.4.5-p14, and 2.4.4-p15, as well as the corresponding B2B versions.

Workarounds

• Restrict access to admin and B2B endpoints with IP allowlisting or VPN-only access until patches are deployed.
• Place a web application firewall in front of the storefront to inspect and rate-limit authenticated requests to sensitive APIs.
• Tighten customer group and role permissions to the minimum required for business operations.
