Details

The default authentication service misses to invalidate empty strings as password. Therefore it is possible to authenticate backend and frontend users without password set in the database. Note: TYPO3 does not allow to create user accounts without a password. Your TYPO3 installation might only be affected if there is a third party component creating user accounts without password by directly manipulating the database.

Is GHSA-6xh8-8pfv-53vx 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 typo3/cms, and gives you the command that fixes it.
