Security readout for executives and security teams
Plain-English summary
CVE-2021-28566 is a low-severity Magento Commerce information disclosure issue. A specially modified PNG uploaded as a product image could reveal the server document root path. The business impact is limited, but exposed paths can help attackers plan follow-on activity.
Executive priority
Handle through normal patch governance unless the affected Magento admin console is broadly exposed. Prioritize faster if the platform handles sensitive commerce operations or has weak admin access controls.
Technical view
Affected Magento Commerce versions include 2.4.2 and earlier, 2.4.1-p1 and earlier, and 2.3.6-p1 and earlier. The weakness is CWE-200 information disclosure during product image upload. The source text says admin console access is required, while also describing an unauthenticated attacker; treat that access condition as evidence requiring confirmation.
Likely exposure
Exposure is most likely on internet-facing Magento Commerce deployments running the listed versions where product image upload functionality is reachable through the admin console.
Exploitation context
No CISA KEV listing or provided source indicates active exploitation. Exploitation requires a specially crafted PNG upload and, according to the description, access to the admin console.
Researcher notes
Evidence supports low confidentiality impact only, with no integrity or availability impact. The access requirement is inconsistent in the description, so validation should confirm the real privilege boundary in the target deployment.
Mitigation direction
- Review Adobe APSB21-30 and apply the applicable Magento security update.
- Restrict admin console access to trusted networks and users.
- Limit product image upload permissions to necessary administrators.
- Monitor Adobe guidance for affected and fixed version details.
Validation and detection
- Inventory Magento Commerce versions against the affected version ranges.
- Confirm the APSB21-30 security update or later supported release is installed.
- Review admin access controls for product image upload capability.
- Check logs for unusual product image upload failures or path disclosure errors.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
