Details

JSON:API PATCH requests may bypass validation for certain fields.

By default, JSON:API works in a read-only mode which makes it impossible to exploit the vulnerability. Only sites that have the read_only set to FALSE under jsonapi.settings config are vulnerable.

Is DRUPAL-CORE-2020-006 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 drupal/core, and gives you the command that fixes it.
