TYPO3 6.2.0 to 6.2.38 ELTS and 7.0.0 to 7.1.0 included a vulnerable external component, which could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack on a targeted system.
Is GHSA-qvhv-pwww-53jj 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.
