TYPO3 CMS Stores Cleartext Password in User Settings Module

Publicada: 24.04.2026
Actualizado: 11.10.2026 10:22

Problem

The backend user settings module (SetupModuleController) incorrectly conflates entity data (like passwords or email address) with user-interface settings (like theme, display options) when persisting changes. As a result, passwords were stored in cleartext in the uc and user_settings fields of the be_users database table.

The cleartext data was only persisted if users changed their credentials in the backend user settings module when the TYPO3 14.2.0 release was used (not in any other version).

Solution

Update to TYPO3 version 14.3.0 LTS which fixes the problem described.

[!IMPORTANT] Manual actions required

Updating to the patched release does not retroactively clean existing data. It is recommended to execute all User Settings upgrade wizards in the TYPO3 Install Tool, including the dedicated User Settings Scrubbing wizard, which sanitizes the incorrectly persisted cleartext values from the uc and user_settings fields of the be_users table. Additionally, affected backend user accounts should be assigned new passwords.

Admin Tools → Upgrade → Upgrade Wizard → User Settings Scrubbing
