Details
As written in the advisory (Markdown source, shown as plain text).
### Problem
Backend users with write access to the `form_definition` database table were able to directly create, update, or delete form definition records via `DataHandler`, bypassing the Form Framework's persistence validation and permission checks. This allowed injecting arbitrary form configurations, re-enabling attack vectors originally addressed in [TYPO3-CORE-SA-2018-003](https://typo3.org/security/advisory/typo3-core-sa-2018-003), including SQL injection and privilege escalation.
### Solution
Update to TYPO3 version 14.3.3 LTS that fixes the problem described.
### Credits
TYPO3 CMS thanks Selçuk Güney for reporting this issue, and to TYPO3 core & security team member Oliver Hader for fixing it.
