I'd like to take a swing at this one, if nobody else is working on it.

I forgot to mention (and should probably add a note to the issue template about it), that if you need a vulnerable server to test your PoC against, there's this project called vulhub that provides docker-compose files for most all of the CVEs for Open Source projects. They even have one for CVE-2023-46604.
