Details

In Concrete CMS (formerly concrete 5) below 8.5.7, IDOR Allows Unauthenticated User to Access Restricted Files If Allowed to Add Message to a Conversation.To remediate this, a check was added to verify a user has permissions to view files before attaching the files to a message in "add / edit message”.

Is GHSA-m2v2-8227-59f5 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 concrete5/core, and gives you the command that fixes it.
