SheetJS Pro through 0.16.9 allows attackers to cause a denial of service (memory consumption) via a crafted .xlsx document that is mishandled when read by xlsx.js (issue 2 of 2).

Is GHSA-8vcr-vxm8-293m 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 xlsx, and gives you the command that fixes it.
