Hello @crackatoa,
The testbed is lacking the steps to reproduce the vulnerability manually. In order to have a complete testbed you should add those.
This can be done via a sequence of shell command, or by providing a script. Obviously everything should be commented accordingly in order to understand clearly what's trigger the vulnerability.

Feel free to reach out
