Craft CMS has potential RCE when PHP register_argc_argv config setting is enabled

CVE-2024-56145GHSA-2p6p-9rc9-62j9

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (craftcms/cms 5.5.2, 4.13.2, 3.9.14), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2024-56145

Advisory: Craft CMS has potential RCE when PHP `register_argc_argv` config setting is enabled
IDs: CVE-2024-56145, GHSA-2p6p-9rc9-62j9
Record: https://patchnext.com/advisories/cve-2024-56145 (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: Critical (CVSS 9.3)
Exploitation: confirmed: listed in the CISA Known Exploited Vulnerabilities catalog.
Vendor response: Vendor fix available; fixed versions by package: craftcms/cms 5.5.2, 4.13.2, 3.9.14. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist craftcms/cms: affected >= 5.0.0-RC1, < 5.5.2; >= 4.0.0-RC1, < 4.13.2; >= 3.0.0, < 3.9.14; fixed in 4.13.2, 3.9.14, 5.5.2

## Suggested inspection (read-only)
- Packagist craftcms/cms: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on craftcms/cms.
- 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?
- Mark the work resolved only after the fixed version is verified in production.
