The login page has an observable timing discrepancy that allows unauthenticated attackers to enumerate registered email addresses. The impact is limited to disclosing whether an account exists for a given email.
Is GHSA-5w46-g9pq-wh6f 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 filament/filament, and gives you the command that fixes it.
