# Patch Next advisory brief: CVE-2024-45120

Advisory: Magento Open Source Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability
IDs: CVE-2024-45120, GHSA-47jp-46c9-25vf
Record: https://patchnext.com/advisories/cve-2024-45120 (revision 1, source checked 26 Oct 2026, 14:26 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
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 2.4.7-p3, 2.4.6-p8, 2.4.5-p10, 2.4.4-p11. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist magento/community-edition: affected >= 2.4.7-beta1, < 2.4.7-p3; >= 2.4.6-p1, < 2.4.6-p8; >= 2.4.5-p1, < 2.4.5-p10; < 2.4.4-p11; >= 2.4.7, <= 2.4.7; >= 2.4.6, <= 2.4.6; >= 2.4.5, <= 2.4.5; >= 2.4.4, <= 2.4.4; fixed in 2.4.5-p10, 2.4.4-p11, 2.4.6-p8, 2.4.7-p3

## Suggested inspection (read-only)
- 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/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.
