The answer to this question is out there, but the reports are not published yet.
I caution readers to not make rash judgements on their skill like this though. These bugs are really hard to find, and it was a minor miracle that I noticed these ones at all. I actually had a whole list of critical bugs in this codebase ready to report before the V2 upgrade was merged to master (which would put it in scope for a bounty). However the auditors managed to find every single bug on my list. I only noticed the ones that eventually made it here later, by a stroke of luck, and after I had already spent a ton of time looking at this codebase without noticing them.
