Problem

The export functionality fails to limit the result set to allowed columns of a particular database table. This allows authenticated users to export internal details of database tables to which they already have access.

Solution

Update to TYPO3 versions 7.6.57 ELTS, 8.7.47 ELTS, 9.5.35 ELTS, 10.4.29, 11.5.11 that fix the problem described above.

In order to address this issue, access to mentioned export functionality is completely denied for regular backend users.

ā„¹ļø Strong security defaults - Manual actions required
Following User TSconfig setting would allow using the export functionality for particular users:

options.impexp.enableExportForNonAdminUser = 1

Credits

Thanks to TYPO3 core merger Lina Wolf who reported this issue and to TYPO3 security member Torben Hansen who fixed the issue.
