Problem

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.

Solution

Update to TYPO3 versions 8.7.41 ELTS, 9.5.28, 10.4.18, 11.3.1 that fix the problem described.

Is GHSA-6mh3-j5r5-2379 in any of your client repos?

Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected typo3/cms-core, and gives you the command that fixes it.
