CVE-2026-47998: Adobe Commerce Auth Bypass Vulnerability

CVE-2026-47998 Overview

Adobe Commerce contains an Incorrect Authorization vulnerability [CWE-863] that allows an attacker to bypass security controls and gain unauthorized read access to protected resources. The flaw affects multiple versions of Adobe Commerce, Adobe Commerce B2B, Magento Open Source, and Adobe I/O Events for Commerce. Exploitation occurs over the network without authentication or user interaction, though success depends on conditions outside the attacker's control. Adobe published the corresponding security advisory APSB26-73 covering this issue.

Critical Impact
An unauthenticated network attacker can bypass authorization checks in Adobe Commerce to read sensitive data when specific runtime conditions are met.

Affected Products

Adobe Commerce (versions 2.4.4 through 2.4.9, including patch releases)
Adobe Commerce B2B (versions 1.3.3 through 1.5.3, including patch releases)
Adobe Magento Open Source (versions 2.4.6 through 2.4.9) and Adobe I/O Events for Commerce

Technical Details for CVE-2026-47998

Vulnerability Analysis

The vulnerability stems from an incorrect authorization decision within Adobe Commerce request handling. The platform performs an authorization check that does not correctly evaluate the caller's privileges against the resource being requested. When the condition is met, an unauthenticated attacker can retrieve data that should be restricted to authorized users.

The impact is limited to confidentiality. Integrity and availability of the Commerce store are not affected by this specific flaw. However, the exposed data can include commerce records, configuration values, or metadata that assist further attacks against the storefront or admin interfaces.

Root Cause

The root cause is a missing or incorrect authorization enforcement pattern classified as [CWE-863] Incorrect Authorization. The affected code path validates a request without correctly verifying whether the requester holds the required entitlement for the target object. This class of flaw commonly appears when access control is applied at one layer (for example, route or controller) but bypassed by an alternate entry point that reaches the same underlying data.

Attack Vector

The attack is delivered over the network against an internet-facing Adobe Commerce instance. No credentials and no user interaction are required. Exploitation depends on conditions outside the attacker's control, such as store configuration, feature enablement, or the presence of specific resources. When those conditions are met, the attacker issues crafted HTTP requests to reach the vulnerable endpoint and receive protected data in the response.

No public proof-of-concept exploit is available at the time of publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Detection Methods for CVE-2026-47998

Indicators of Compromise

Unauthenticated HTTP requests to Adobe Commerce API or storefront endpoints returning data typically gated by authentication or role checks.
Anomalous spikes in 200 OK responses for endpoints that historically returned 401 or 403 for the same client identity.
Repeated enumeration patterns against Commerce REST or GraphQL endpoints from a single source IP or ASN.

Detection Strategies

Review web server and application logs for access to sensitive Commerce endpoints without a preceding authentication event.
Correlate request paths with the affected components listed in Adobe advisory APSB26-73 and alert on access from unauthenticated sessions.
Baseline normal API consumers (integration accounts, storefront) and flag deviations in User-Agent, request volume, or endpoint mix.

Monitoring Recommendations

Enable verbose logging for Commerce authorization decisions and forward logs to a SIEM for retention and correlation.
Monitor egress data volumes from the Commerce application tier to identify bulk data reads consistent with authorization bypass.
Track outbound traffic to the storefront domain from unusual geographies or hosting providers frequently associated with scraping.

How to Mitigate CVE-2026-47998

Immediate Actions Required

Inventory all Adobe Commerce, Commerce B2B, and Magento Open Source deployments and confirm running versions against the affected list.
Apply the security update referenced in the Adobe advisory APSB26-73 on the next available maintenance window.
Restrict administrative and API endpoints to trusted networks using firewall or web application firewall (WAF) rules until patches are deployed.

Patch Information

Adobe has released fixed versions for Adobe Commerce, Adobe Commerce B2B, Adobe Magento Open Source, and Adobe I/O Events for Commerce. Refer to the Adobe Magento Security Advisory APSB26-73 for the specific patched versions and upgrade instructions applicable to each product line.

Workarounds

Deploy WAF rules to block anomalous or unauthenticated requests to sensitive Commerce API paths pending patch deployment.
Enforce rate limiting on Commerce REST and GraphQL endpoints to slow enumeration attempts that rely on the bypass condition.
Restrict access to non-storefront endpoints, such as admin and integration APIs, to allow-listed IP ranges where feasible.

bash

# Example nginx configuration to restrict Commerce admin and REST endpoints
location ~* ^/(admin|rest/all|rest/V1) {
    allow 10.0.0.0/8;         # internal management network
    allow 203.0.113.0/24;     # trusted integration partner
    deny all;
    limit_req zone=commerce_api burst=20 nodelay;
    proxy_pass http://commerce_backend;
