Is GHSA-xmjh-wjc5-wg4h 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 silverstripe/cms, and gives you the command that fixes it.

Scan a project free, no signup Or connect GitHub to scan every repo
