Description
Backend users were able to insert arbitrary records and files into the TYPO3 clipboard without proper read permission checks, which allowed users to gather information about records and files they were not authorized to view. This issue affects TYPO3 CMS versions 10.4.0-13.4.30 and 14.0.0-14.3.2.
