Failing to properly encode information from external sources, language pack handling in the install tool is vulnerable to cross-site scripting.

Is GHSA-76r3-m635-p3vc 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.
