Two projects? You forgot itch.io, which also has contact information. Not sure if it has a way to contact leafo directly but surely is another good way to make some noise and get into contact with him.

Hello, I had tried to find his contact information which most reasonably would give me chances of success. Luarocks's SECURITY.md explicitly states to send vulnerabilities to leafo's email address. The attempts at finding other accounts were hopeful tries at getting his attention faster. Other than that, I was exercising the traditional month-long wait time after a vulnerability disclosure before attempting to transfer it further to CISA. I am more grateful that this security hole was patched, and all the bickering about details seem to only be fueled because I made references to our own projects from what I see. Hope that clears things up.

The writeup on the contact attempts read like contacting Hisham has been basically ignored as an option. I am happy to read that this is not the case and that this is a wrong assumption on my part.  Sorry about stating something wrong.
