Details

Failing to sanitize content from editors, the legacy form component is susceptible to Cross-Site Scripting. A valid editor account with access to a form content element is required to exploit this vulnerability.

Is GHSA-vgm8-r9gm-fw59 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.
