Details

TYPO3 4.0.x before 4.0.9, 4.1.x before 4.1.7, and 4.2.x before 4.2.1, uses an insufficiently restrictive default fileDenyPattern for Apache, which allows remote attackers to bypass security restrictions and upload configuration files such as .htaccess, or conduct file upload attacks using multiple extensions.

Is GHSA-f35p-hcwf-9f9f 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.
