Security readout for executives and security teams
Plain-English summary
This flaw lets a signed-in Magento Commerce admin with limited privileges change customer data they should not control. It is not described as remotely exploitable without an admin account, but it can still create business risk where many staff or vendors have admin console access.
Executive priority
Treat as a moderate-priority access-control issue. Prioritize remediation for stores with many admin users, outsourced operations, or sensitive customer records.
Technical view
CVE-2021-28567 is an improper authorization issue in the Magento Commerce customers module. A low-privileged authenticated admin user could modify customer data. The listed affected versions are 2.4.2 and earlier, 2.4.1-p1 and earlier, and 2.3.6-p1 and earlier. CVSS is 5.0.
Likely exposure
Exposure is most likely in Adobe Magento Commerce deployments on the affected version ranges with active admin console accounts for support, operations, agencies, or vendors.
Exploitation context
The source bundle does not report active exploitation, and KEV is false. Exploitation requires admin console access and low privileges, with high attack complexity per CVSS.
Researcher notes
This is CWE-285 with PR:L, AC:H, UI:N, and low confidentiality, integrity, and availability impact. The key boundary is Magento admin authorization within the customers module, not unauthenticated storefront access.
Mitigation direction
- Review Adobe APSB21-30 for the appropriate security update path.
- Upgrade affected Magento Commerce branches according to Adobe guidance.
- Restrict admin console access to trusted users only.
- Review low-privileged admin roles that can access customer management.
- Remove stale vendor, contractor, and shared admin accounts.
Validation and detection
- Inventory Magento Commerce versions across all stores and environments.
- Confirm whether any instance matches the affected version ranges.
- Review admin role assignments for customer data permissions.
- Audit recent customer data changes by low-privileged admin accounts.
- After updating, verify customer management permissions match intended roles.

Improper Authorization
Improper Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
