Details

It has been discovered that the Form Framework (system extension form) is vulnerable to Insecure Deserialization when being used with the additional PHP PECL package yaml, which is capable of unserializing YAML contents to PHP objects. A valid backend user account as well as having PHP setting yaml.decode_php enabled is needed to exploit this vulnerability (which is the default value according to PHP documentation).

Is GHSA-96jg-pmc4-cx39 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-core, and gives you the command that fixes it.
