What a frustrating article. There was an interesting bug here. It's trivial to explain. It's not a zero-day, this was fixed months before disclosure. Most of the article is basically: "Imagine you were running software with horrific security holes behind this WAF. We even made some examples. It had a flaw. If your entire security posture depended on this WAF, imagine how much damage could have been done. Imagine if AI were involved!"

On top of that, AI was clearly used to write it which made it longer than necessary and harder to read.
