CVE-2026-48412 Overview
Adobe Commerce contains an Incorrect Authorization vulnerability [CWE-863] that enables privilege escalation. An attacker holding high-privilege credentials can leverage the flaw to access restricted resources beyond their assigned authorization boundary. Exploitation requires no user interaction and occurs over the network.
The issue affects Adobe Commerce (formerly Magento) and is documented in Adobe Security Bulletin APSB26-92. While the CVSS score reflects limited direct impact on confidentiality and integrity, incorrect authorization in a commerce platform can expose administrative functions, order data, and customer records to actors who should not access them.
Critical Impact
An authenticated high-privilege attacker can escalate access to restricted resources within Adobe Commerce, bypassing intended authorization controls without any user interaction.
Affected Products
- Adobe Commerce (per Adobe Security Bulletin APSB26-92)
- Magento Open Source (per Adobe Security Bulletin APSB26-92)
- Specific affected versions are enumerated in the Adobe Security Advisory for Magento

Technical Details for CVE-2026-48412
Vulnerability Analysis
The vulnerability is classified under [CWE-863]: Incorrect Authorization. The application performs an authorization check, but the check does not correctly enforce the intended access policy. As a result, an authenticated user with elevated privileges can reach resources or actions that should remain outside their role scope.
Adobe categorizes the flaw as a privilege escalation issue with network attack vector and no user interaction. The confidentiality impact is none and the integrity impact is low, indicating the attacker gains limited ability to modify data through the escalated access path. Availability is unaffected.
Because exploitation requires high privileges, this is not a pre-authentication vulnerability. It is most relevant in Adobe Commerce environments where multiple administrative or reseller roles exist and where separation of duties depends on the platform's role-based access controls.
Root Cause
The root cause is an authorization logic flaw in Adobe Commerce that fails to fully restrict actions based on the caller's role. Adobe has not published detailed code-level information. Refer to the Adobe Security Advisory for Magento for vendor-supplied technical context.
Attack Vector
The attack originates over the network against the Adobe Commerce application. The attacker authenticates with a high-privilege account, then invokes an application function or API endpoint whose authorization check does not correctly gate the operation. The result is access to a restricted resource or the ability to perform a privileged action outside the attacker's assigned scope.
No verified exploit code is publicly available. No entry exists in the CISA Known Exploited Vulnerabilities catalog. The EPSS score is 0.315% (24th percentile), indicating a low near-term probability of observed exploitation.
Detection Methods for CVE-2026-48412
Indicators of Compromise
- Authenticated administrative sessions accessing endpoints or resources outside the account's usual role scope.
- Unexpected modifications to catalog, order, customer, or configuration data performed by accounts that should lack such permissions.
- API calls from admin users to routes not associated with their assigned role in prior baselines.
Detection Strategies
- Enable and centralize Adobe Commerce admin action logs, then alert on role-to-action mismatches.
- Baseline each administrative role's typical endpoint usage and flag deviations for review.
- Correlate authentication events with subsequent privileged operations to spot escalation chains.
Monitoring Recommendations
- Ingest Adobe Commerce web server, application, and admin audit logs into a central SIEM for retention and correlation.
- Monitor for repeated 200-OK responses on administrative endpoints from accounts that historically only accessed a narrow subset.
- Track changes to admin user roles, permissions, and ACL rules and alert on out-of-window modifications.
How to Mitigate CVE-2026-48412
Immediate Actions Required
- Apply the Adobe Commerce security update referenced in Adobe Security Advisory APSB26-92 to all affected instances.
- Audit administrative accounts and remove or downgrade any account that does not require elevated privileges.
- Rotate credentials for high-privilege admin users, particularly shared or service accounts.
- Review role definitions and confirm least-privilege assignment before and after patching.
Patch Information
Adobe has released fixes as documented in Adobe Security Bulletin APSB26-92. Administrators should consult the Adobe Security Advisory for Magento for the specific patched versions applicable to their Adobe Commerce or Magento Open Source deployment and apply the update through the standard Composer or patch installation process.
Workarounds
- Restrict access to the Adobe Commerce admin interface using network-level controls such as IP allowlists or VPN gating until patching is complete.
- Enforce multi-factor authentication on all administrative accounts to reduce the risk of high-privilege account compromise.
- Temporarily reduce the number of accounts assigned high-privilege roles while remediation is in progress.
