### Problem
Failing to properly encode settings for _backend layouts_, the corresponding grid view is vulnerable to persistent cross-site scripting. A valid backend user account is needed to exploit this vulnerability.
### Solution
Update to TYPO3 versions 8.7.41 ELTS, 9.5.28, 10.4.18, 11.3.1 that fix the problem described.
### Credits
Thanks to TYPO3 core merger Oliver Bartsch who reported and fixed the issue.
