TYPO3 CMS has Broken Access Control in its DataHandler

CVE-2026-47350GHSA-qcmw-6rm2-5x78

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (typo3/cms-core 14.3.3, 13.4.31), 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-2026-47350

Advisory: TYPO3 CMS has Broken Access Control in its DataHandler
IDs: CVE-2026-47350, GHSA-qcmw-6rm2-5x78
Record: https://patchnext.com/advisories/cve-2026-47350 (revision 1, source checked 26 Oct 2026, 14:49 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: Vendor fix available; fixed versions by package: typo3/cms-core 14.3.3, 13.4.31. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist typo3/cms-core: affected >= 13.0.0, < 13.4.31; >= 14.0.0, < 14.3.3; fixed in 13.4.31, 14.3.3

## Suggested inspection (read-only)
- Packagist typo3/cms-core: 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 typo3/cms-core.
- 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.

## Sources
- Verified: https://github.com/advisories/GHSA-qcmw-6rm2-5x78 (GitHub-reviewed advisory GHSA-qcmw-6rm2-5x78 lists affected ranges: Packagist typo3/cms-core >=13.0.0 =14.0.0 <14.3.3)
