Not sure what you are apologizing for. It's a severely overblown bug that ended up on the front page of New York Times and the Japan Prime Minister had to get involved too. The bug itself is non trivial to exploit from just public requests to a web server so I am not sure what the hysteria is about. It's no different from the other hundred or so CVEs I see being posted or dropped everyday.
It will be headlines on Hacker News regardless due to sheer sensationalism, I think most DevSecOps people would rather find out the news here first than via their boss calling them after reading the morning news.
What does "non trivial to exploit from just public requests" mean? It's known to be exploitable on more than one stock PHP application. This really is a 5-alarm fire.
I think people are just latching onto the post that hit the front page earlier today about it being non-trivial to exploit, combined with the fact that there seem to be about a billion PoC out there, most of which don't work.
Right, that's what's worrying me. It is not interesting that the most widely circulated public POC/demos don't work. All you should care about is the (currently) non-public POCs that do work, of which there are apparently several.
The most direct exploit requires a compromised supply chain which ranks it about as dangerous as your usual dependency exploits.

My PoC (generated) was able to exploit an index.php with a simple echo.
The only thing you have to know in advance is the relative memory offset distances, and that's it. Memory feng shui was the longest part of the implementation.

Did you even read the diff, it synthesized intentionally vulnerable code which trivializes the exploitability

The Japanese PM did not “have” to get involved.
Well, consider that their old IT minister has never used a computer in his life, it's probably a good thing she's the one issuing the call to update.
You've used a computer the moment you aren't even born yet.
