TYPO3 Unverified Password Change for Backend Users

CVE-2025-47938GHSA-3jrg-97f3-rqh9

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (typo3/cms-setup 13.4.12, 12.4.31, 11.5.44, 10.4.50, 9.5.51; typo3/cms-core 13.4.12, 12.4.31, 11.5.44, 10.4.50, 9.5.51), 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.

Source description

As published by the source; long descriptions are shortened.

Problem The backend user management interface allows password changes without requiring the current password. When an administrator updates their own account or modifies other user accounts via the admin interface, the current password is not requested for verification. This behavior may lower the protection against unauthorized access in scenarios where an admin session is hijacked or left unattended, as it enables password changes without additional authentication. Solution Update to TYPO3 versions 9.5.51 ELTS, 10.4.50 ELTS, 11.5.44 ELTS, 12.4.31 LTS, 13.4.12 LTS that fix the problem described. [!NOTE] In these versions, administrators are required to verify their identity through step-up authentication (also known as sudo mode) when changing backend user passwords. Credits Thanks to the National Cyber Security Center (NCSC) of Switzerland for reporting this issue, and to TYPO3 core & security team member Benjamin Franzke for fixing it.

# Patch Next advisory brief: CVE-2025-47938

Advisory: TYPO3 Unverified Password Change for Backend Users
IDs: CVE-2025-47938, GHSA-3jrg-97f3-rqh9
Record: https://patchnext.com/advisories/cve-2025-47938 (revision 1, source checked 26 Oct 2026, 14:33 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 3.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: typo3/cms-setup 13.4.12, 12.4.31, 11.5.44, 10.4.50, 9.5.51; typo3/cms-core 13.4.12, 12.4.31, 11.5.44, 10.4.50, 9.5.51. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist typo3/cms-setup: affected >= 9.0.0, <= 9.5.50; >= 10.0.0, <= 10.4.49; >= 11.0.0, <= 11.5.43; >= 12.0.0, <= 12.4.30; >= 13.0.0, <= 13.4.11; fixed in 13.4.12, 9.5.51, 10.4.50, 11.5.44, 12.4.31
- Packagist typo3/cms-core: affected >= 9.0.0, <= 9.5.50; >= 10.0.0, <= 10.4.49; >= 11.0.0, <= 11.5.43; >= 12.0.0, <= 12.4.30; >= 13.0.0, <= 13.4.11; fixed in 13.4.12, 9.5.51, 10.4.50, 11.5.44, 12.4.31

## Suggested inspection (read-only)
- Packagist typo3/cms-setup: check the installed version with your package manager.
- 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-setup, 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.
