Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
TYPO3 CMS packages typo3/cms-core and typo3/cms-form are affected in versions from 14.0.0 before 14.3.3. Backend users with write access to the form_definition database table could create, update, or delete form definitions through DataHandler, bypassing the Form Framework's validation and permission checks, which the source says could enable SQL injection and privilege escalation. Update to TYPO3 14.3.3 LTS, which fixes the problem.
