Failing to properly encode error messages, the components QueryGenerator and QueryView are vulnerable to both reflected and persistent cross-site scripting. A valid backend user account having administrator privileges is needed to exploit this vulnerability.
Update to TYPO3 versions 8.7.41 ELTS, 9.5.28, 10.4.18, 11.3.1 that fix the problem described.
Thanks to Richie Lee who reported this issue and to TYPO3 security team member Oliver Hader who fixed the issue.
