IDs: CVE-2021-36044, GHSA-wr57-3h2f-3q95
Record: https://patchnext.com/advisories/cve-2021-36044 (revision 1, source checked 26 Oct 2026, 14:34 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Partial vendor fix; fixed versions by package: magento/community-edition 2.4.2-p2, 2.3.7-p1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist magento/project-community-edition: affected <= 2.0.2
- Packagist magento/community-edition: affected >= 2.4.2, <= 2.4.2; >= 2.4.2-p1, < 2.4.2-p2; >= 2.3.7, <= 2.3.7; < 2.3.7-p1; fixed in 2.3.7-p1, 2.4.2-p2

## Suggested inspection (read-only)
- Packagist magento/project-community-edition: check the installed version with your package manager.
- Packagist magento/community-edition: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on magento/project-community-edition, magento/community-edition.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
