Security readout for executives and security teams
Plain-English summary
This flaw could let a highly privileged authenticated Magento Commerce user or integration delete customer details through the REST API without proper authorization. It is not a broad unauthenticated compromise, but it can damage customer records and business operations if risky integration permissions exist.
Executive priority
Treat as a moderate-priority integrity risk for affected Magento Commerce stores. Prioritize if customer data operations depend on third-party integrations or many privileged API accounts exist, because the business impact is unauthorized deletion rather than data theft or full system takeover.
Technical view
CVE-2020-24402 is a CWE-276 incorrect-permissions issue in Magento Commerce Integrations. Adobe-listed affected versions include Magento 2.4.0, 2.3.5-p1, and earlier. Abuse requires authenticated access with Resource Access API permissions and impacts integrity by enabling unauthorized customer-detail deletion via REST API.
Likely exposure
Exposure is most likely in Magento Commerce deployments on 2.4.0, 2.3.5-p1, or earlier where users or integrations have Resource Access API permissions. The source bundle does not identify unauthenticated exposure or other affected Adobe products.
Exploitation context
The CVSS vector shows network reachability, low complexity, high privileges required, and no user interaction. The source bundle marks CISA KEV as false and provides no evidence of active exploitation or public weaponization.
Researcher notes
Evidence is limited to the CVE description, CVSS vector, CWE-276 classification, affected Magento Commerce versions, and Adobe bulletin reference. Do not assume exploitation in the wild, unauthenticated access, or fixed-version details beyond what Adobe APSB20-59 confirms.
Mitigation direction
- Check Adobe APSB20-59 and apply the vendor-recommended Magento security update for affected versions.
- Inventory Magento Commerce versions and prioritize systems at 2.4.0, 2.3.5-p1, or earlier.
- Review integrations and users with Resource Access API permissions for least-privilege scope.
- Remove unused integrations and unnecessary REST API permissions.
- Ensure backups and recovery procedures cover customer record deletion scenarios.
Validation and detection
- Confirm deployed Magento Commerce versions against the affected versions in the CVE record.
- List users and integrations granted Resource Access API permissions.
- Review audit logs for unexpected customer deletion activity through REST API paths.
- Verify vendor security guidance or update status from Adobe APSB20-59.
- Test that non-authorized integration roles cannot delete customer details.
