Details

Multiple cross-site scripting (XSS) vulnerabilities in the Backend subcomponent in TYPO3 4.0.13 and earlier, 4.1.x before 4.1.13, 4.2.x before 4.2.10, and 4.3.x before 4.3beta2 allow remote authenticated users to inject arbitrary web script or HTML via unspecified vectors.

Is GHSA-g857-p997-wx7w 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-backend, and gives you the command that fixes it.
