Failing to properly encode user input, some backend components are vulnerable to Cross-Site Scripting. A valid backend user account is needed to exploit this vulnerability.
Is GHSA-86r8-4g3w-7xjp 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, and gives you the command that fixes it.
