The vulnerability centers on missing access controls for translatable field exports. TYPO3 backend modules typically use Controller actions for export functionality, and service classes for rendering. The advisory specifically mentions export-related information disclosure, implicating the export action handler and XML renderer. While exact code changes aren't visible, these components would logically require the added authorization checks mentioned in the advisory. Confidence is medium due to inference from vulnerability patterns in TYPO3 extensions rather than direct patch analysis.
