CVE-2026-49741
TYPO3 CMS has Privilege Escalation & SQL Injection in its Form Framework
描述
### 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. ### Resources * [TYPO3-CORE-SA-2026-017](https://typo3.org/security/advisory/typo3-core-sa-2026-017)
