CVE-2026-92910: Adobe Commerce Auth Bypass Vulnerability

CVE-2026-92910 Overview

CVE-2026-92910 is an Incorrect Authorization vulnerability [CWE-863] affecting Adobe Commerce. The flaw allows a remote attacker to bypass security controls and gain unauthorized read access and limited write access to the application. Exploitation does not require user interaction or authentication, and the scope is changed, meaning the impact extends beyond the vulnerable component. Adobe disclosed the issue in Security Bulletin APSB26-153.

Critical Impact
An unauthenticated remote attacker can bypass authorization checks in Adobe Commerce to read sensitive data and perform limited write operations across trust boundaries.

Affected Products

Adobe Commerce (see Adobe Security Bulletin APSB26-153 for affected versions)
Magento Open Source editions covered under the same bulletin
Deployments relying on default Adobe Commerce authorization logic

Technical Details for CVE-2026-92910

Vulnerability Analysis

The vulnerability is classified as Incorrect Authorization [CWE-863]. Adobe Commerce performs authorization checks that do not correctly enforce access boundaries for certain operations. An unauthenticated attacker reachable over the network can send crafted requests that bypass these checks.

Successful exploitation yields unauthorized read access and limited write access. Because the CVSS scope is marked as changed, the impact crosses a trust boundary and can affect resources managed by components other than the vulnerable one. This increases the blast radius of a single request beyond the directly exposed endpoint.

The flaw does not require user interaction and the attack complexity is low, making it suitable for automated exploitation against exposed storefronts and admin interfaces. Adobe has published remediation details in Security Bulletin APSB26-153.

Root Cause

The root cause is improper enforcement of authorization rules on specific Adobe Commerce functionality. The application evaluates access decisions using logic that does not account for all request contexts, allowing an attacker to reach protected operations without the required privileges. CWE-863 describes this class of defect, where authorization code exists but is incorrectly implemented.

Attack Vector

The attack vector is network-based. An attacker sends HTTP requests to a reachable Adobe Commerce instance targeting the vulnerable authorization path. No credentials, prior access, or victim interaction are required. Because the scope changes, the attacker may read data or trigger limited writes affecting resources outside the component that performed the flawed check.

No verified proof-of-concept code is publicly available at the time of writing. Technical specifics are described in the Adobe Security Bulletin APSB26-153.

Detection Methods for CVE-2026-92910

Indicators of Compromise

Unexpected HTTP 200 responses to administrative or privileged Adobe Commerce endpoints originating from unauthenticated sessions.
Access log entries showing requests to protected resources without preceding authentication requests.
Unexplained modifications to customer, order, catalog, or configuration records that cannot be tied to a valid admin session.

Detection Strategies

Review web server and application logs for requests to Adobe Commerce REST, GraphQL, and admin endpoints that return privileged data without an authenticated session cookie or bearer token.
Correlate database write events in Adobe Commerce with the originating session identifier to flag writes lacking a valid authenticated principal.
Deploy virtual patching rules on web application firewalls using the signatures referenced in Adobe Security Bulletin APSB26-153 once published.

Monitoring Recommendations

Monitor outbound data volume from Adobe Commerce application servers for anomalies indicating bulk read access.
Alert on configuration changes, admin role modifications, and catalog edits performed outside standard change windows.
Track repeated requests from a single source IP against authorization-sensitive URIs and rate-limit or block at the edge.

How to Mitigate CVE-2026-92910

Immediate Actions Required

Apply the Adobe Commerce security update referenced in Adobe Security Bulletin APSB26-153 to all production and staging instances.
Inventory internet-exposed Adobe Commerce deployments and prioritize patching for storefronts handling payment or personally identifiable information.
Rotate API keys, integration tokens, and administrative credentials that could have been exposed through unauthorized read access.

Patch Information

Adobe has released patched versions of Adobe Commerce as described in Security Bulletin APSB26-153. Administrators should review the bulletin for the exact fixed versions matching their deployment branch and apply updates through the standard Adobe Commerce patch workflow or Composer upgrade path.

Workarounds

Restrict network access to Adobe Commerce admin and API endpoints using IP allowlisting at the load balancer or web application firewall.
Deploy WAF rules that block anonymous requests to authorization-sensitive paths until the patch is applied.
Enable detailed audit logging on authentication, authorization, and administrative actions to support rapid incident response.

bash

# Example: restrict Adobe Commerce admin path at the Nginx edge
location ^~ /admin {
    allow 10.0.0.0/8;
    deny all;
    proxy_pass http://commerce_backend;
}
