CVE-2026-95630: Adobe Commerce Auth Bypass Vulnerability

CVE-2026-95630 Overview

Adobe Commerce contains an improper input validation vulnerability [CWE-20] that allows a low-privileged attacker to bypass security controls and gain unauthorized read access. The flaw is exploitable over the network without user interaction. Adobe disclosed the issue in security bulletin APSB26-153 and tracks it as a security feature bypass with limited confidentiality impact. The vulnerability does not affect integrity or availability, but it exposes data that should remain protected by Adobe Commerce access controls.

Critical Impact
An authenticated attacker with low privileges can bypass security measures in Adobe Commerce to read data outside their authorization scope, without any user interaction.

Affected Products

Adobe Commerce (see Adobe Security Bulletin APSB26-153 for affected version ranges)

Technical Details for CVE-2026-95630

Vulnerability Analysis

Adobe Commerce fails to properly validate input in a code path that enforces access restrictions. An attacker who holds a low-privileged account can submit crafted input that bypasses the intended security check. The platform then returns data that the attacker should not be able to read.

The issue is classified as a security feature bypass rather than a direct authorization flaw. The underlying authorization logic exists but can be circumvented through malformed or unexpected input. Exploitation requires network access to the Commerce storefront or admin interface and a valid authenticated session. User interaction is not required, which makes the issue suitable for automated abuse against exposed Commerce instances.

Impact is limited to unauthorized read access. The vulnerability does not permit modification of records or disruption of service. However, Adobe Commerce environments commonly process customer records, order history, and pricing data, so read-only exposure still carries data protection consequences.

Root Cause

The root cause is improper input validation [CWE-20] within an Adobe Commerce component that performs an authorization or security check. The component accepts input that falls outside the expected validation rules, which routes the request past the intended security control. Adobe has not published low-level technical details of the affected function in the public advisory.

Attack Vector

The attack vector is network-based. An attacker authenticates to Adobe Commerce with a low-privileged account, such as a standard customer or restricted admin role, then sends a crafted request containing input that bypasses validation. The server processes the request and returns restricted data. Because no user interaction is required, exploitation can be scripted against any reachable Adobe Commerce endpoint.

For full exploitation details and affected version ranges, consult the Adobe Security Bulletin APSB26-153.

Detection Methods for CVE-2026-95630

Indicators of Compromise

Unexpected read requests from low-privileged accounts targeting admin or restricted REST and GraphQL endpoints
Access log entries containing malformed parameters or unusual encoding in requests to Adobe Commerce APIs
Spikes in authenticated requests from a single session enumerating customer, order, or catalog resources

Detection Strategies

Review Adobe Commerce application logs for authenticated requests that return data normally restricted to higher-privileged roles
Correlate web server access logs with Commerce audit logs to identify sessions that access resources outside their expected scope
Deploy web application firewall rules that flag input anomalies on Adobe Commerce API routes referenced in APSB26-153

Monitoring Recommendations

Enable verbose logging on Adobe Commerce REST, GraphQL, and admin endpoints for the duration of patching
Forward Commerce and web server logs to a centralized analytics platform for anomaly detection on authenticated session behavior
Alert on repeated 200 responses to low-privileged users accessing resources tagged as sensitive, such as /rest/V1/customers or admin API routes

How to Mitigate CVE-2026-95630

Immediate Actions Required

Apply the Adobe Commerce security update referenced in APSB26-153 to all affected instances
Audit existing low-privileged accounts and disable any that are unused or unnecessary
Rotate credentials and session tokens for accounts that may have been active during the exposure window

Patch Information

Adobe released fixed versions of Adobe Commerce in security bulletin APSB26-153. Administrators should identify their current Commerce version, consult the bulletin for the corresponding fixed release, and schedule the upgrade through the standard Composer-based update workflow. Cloud deployments should confirm the patch level applied by Adobe Managed Services.

Workarounds

Restrict network access to the Adobe Commerce admin interface using IP allowlisting at the load balancer or WAF
Enforce the principle of least privilege by reviewing custom role resources and removing unnecessary read permissions
Place a web application firewall in front of Adobe Commerce and enable rulesets that validate request parameters on API endpoints
