CVE-2025-59020Network attack vector

Authenticated prohibited-field writes via trusted defVals

Published Jan 13, 2026 · Updated Jan 13, 2026

Broken access control in TYPO3 CMS allows remote authenticated users to write prohibited database fields through backend requests. EditDocumentController assigns user-controlled defVals to DataHandler's trusted defaultValues instead of routing them through datamap permission checks. A backend account with table write permission can therefore set exclude fields prohibited by its field-level permissions.
