CVE-2025-49556 Overview
CVE-2025-49556 is an Incorrect Authorization vulnerability [CWE-863] affecting Adobe Commerce, Adobe Commerce B2B, and Magento Open Source. The flaw allows a remote, unauthenticated attacker to bypass security controls and gain unauthorized read access to protected resources. Affected versions include Adobe Commerce 2.4.9-alpha1, 2.4.8-p1, 2.4.7-p6, 2.4.6-p11, 2.4.5-p13, 2.4.4-p14, and earlier. Exploitation requires no user interaction and the scope remains unchanged. Adobe addressed the issue in security advisory APSB25-71.
Critical Impact
Unauthenticated attackers can bypass authorization controls and read sensitive data from affected Adobe Commerce and Magento Open Source storefronts.
Affected Products
- Adobe Commerce (versions 2.4.4-p14, 2.4.5-p13, 2.4.6-p11, 2.4.7-p6, 2.4.8-p1, 2.4.9-alpha1, and earlier)
- Adobe Commerce B2B (versions 1.3.3 through 1.5.3-alpha1 and earlier)
- Magento Open Source (versions 2.4.5 through 2.4.9-alpha1 and earlier)

Technical Details for CVE-2025-49556
Vulnerability Analysis
The vulnerability stems from improper authorization enforcement within Adobe Commerce and Magento Open Source. Affected code paths fail to correctly validate whether the requesting principal is permitted to access targeted resources. As a result, an attacker can issue crafted network requests and retrieve data that should be restricted to authorized users.
The issue is exploitable over the network without authentication or user interaction. While integrity and availability are not impacted, the confidentiality impact is significant because protected information can be exposed to anonymous callers. The bug is categorized under CWE-863: Incorrect Authorization.
Root Cause
The root cause is an authorization check that does not adequately verify the caller's permissions for a given object or operation. Logic that should restrict access based on role, ownership, or session context allows requests to proceed when they should be denied. Adobe's security bulletin APSB25-71 documents the affected components and fixed builds.
Attack Vector
An attacker sends crafted HTTP requests to a vulnerable Adobe Commerce, Commerce B2B, or Magento Open Source endpoint. Because authentication is not required, exploitation can be automated against internet-facing storefronts. Successful requests return data the caller is not authorized to view, enabling reconnaissance, data harvesting, or staging for follow-on attacks.
No public proof-of-concept exploit code is currently available for this issue. Refer to the vendor advisory for technical context.
Detection Methods for CVE-2025-49556
Indicators of Compromise
- Unauthenticated HTTP requests to Adobe Commerce or Magento endpoints that return data normally requiring authentication.
- Spikes in anonymous traffic targeting REST or GraphQL endpoints associated with customer, order, or catalog data.
- Repeated requests from a single source iterating over object identifiers in API responses.
Detection Strategies
- Inventory all Adobe Commerce, Commerce B2B, and Magento Open Source deployments and compare installed versions against the fixed versions listed in APSB25-71.
- Review web server and application logs for anonymous requests to endpoints that return non-public data.
- Deploy web application firewall (WAF) rules to flag and alert on suspicious unauthenticated access patterns to commerce APIs.
Monitoring Recommendations
- Enable verbose request logging on Adobe Commerce and Magento storefronts and forward logs to a centralized analytics platform.
- Monitor for anomalous response sizes from anonymous sessions, which may indicate bulk data retrieval.
- Correlate WAF, application, and database telemetry to identify authorization bypass attempts across the stack.
How to Mitigate CVE-2025-49556
Immediate Actions Required
- Apply the patches referenced in Adobe security bulletin APSB25-71 to all affected Adobe Commerce, Commerce B2B, and Magento Open Source instances.
- Audit administrator and customer accounts for unauthorized activity dating back to the introduction of the affected releases.
- Restrict exposure of administrative and API endpoints to trusted networks where business requirements allow.
Patch Information
Adobe released fixes in security bulletin APSB25-71. Upgrade Adobe Commerce, Adobe Commerce B2B, and Magento Open Source to the versions identified as fixed in the advisory. Validate the upgrade in a staging environment before deploying to production.
Workarounds
- Deploy WAF rules to block or rate-limit anonymous requests to sensitive REST and GraphQL endpoints until patching is complete.
- Place the storefront admin behind IP allowlists or VPN access where feasible.
- Enforce least-privilege configuration for API integrations and rotate any tokens that may have been exposed.
# Confirm Adobe Commerce / Magento version before and after patching
php bin/magento --version
# Apply the official composer patch package and run upgrade routines
composer require magento/product-community-edition --no-update
composer update
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento cache:flush
