It has been discovered that backend users having limited access to specific languages are capable of modifying and creating pages in the default language which actually should be disallowed. A valid backend user account is needed in order to exploit this vulnerability.

Is GHSA-9rx9-7fmh-gj3g 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.
