I think there's still going to be a massive long tail of sites that will never be protected or upgraded, unfortunately that's the reality. So no amount of delay will help them, and most active sites will have patched by now after 5 days.
There are already many people claiming they have an exploit, some in this thread, I think this is a useful measure of just how easy it is - thankfully it doesn't look too easy as it's still up at time of writing, though surely someone will manage it soon.
If it does get taken quickly I think that's useful information on just how serious this is.
If it doesn't, that's also useful info though not hard proof there is no exploit. It does mean that there is no exploit in the hands of script kiddies with chatgpt or similar.

Ok? But that's super common, and there's thousands of ways to exploit unmaintained systems, nothing special about this.
From a technical level as well, this is not an easy bug to exploit, it's CVSS Attack Complexity:High, it requires a lot of per-target work, it's definitely not copy.fail level
I think we’re saying the same thing - at this stage there’s not much point in withholding details,
That’s why I brought up the sites that will
never patch - that’s normal and at some point it helps more to release more details.
Shared host Wordpress sites basically run in unprotected untrusted mode since WP has so many RCEs already and they can be in any random plugin someone adds at any time. So even if there's an RCE a lot of these sites just shrug at the attack. You would need to figure out how to chain it for something useful.
I'm not sure what this page proves except that not all set-ups are in danger. Especially if the site does nothing and has a nginx in front that caps all requests to 1mb.
There are, afaict, at least half a dozen choices a PHP server could have made that mitigates all (known) exploits. Putting some bitcoins behind one of them isn't exactly proof of anything, except as a PR stunt to convince people PHP is not a pile of tightly coupled hot-c garbage.

Other projects that get CVEs talk about what went wrong and how to improve. So far i've only seen PHP people defensive and telling each other that ok because other projects also get CVEs.
But the Dutch government websites do generally (I hope) have users, which is one of the ways the "I need to hit the same php worker, uninterrupted, for about 10 to 30 seconds while absolutely no other traffic hits the site AND I can isolate the one worker from the pool" approach to exploiting fails.
Luck is not a security boundary, they should patch their servers, everyone should. It's not a good thing to have shitty memory management on your server.
However, is this really that exploitable in real world conditions? (no)
"There does not exists" and "I've not heard off" are different things. This is motivated reasoning on your part to tell the story that this isn't a big deal.
Most variants require a few requests to infer some settings, and then they can spam their arming-stage, and then their exploit stage. Granted, its not quite as easy as that, but hitting _a_ worker twice on a server once is not all that lucky.
So according to you they could have just imposed an upload cap instead and been safe? If all the cybersecurity experts had given useful advice like that earlier in the week people could have been safer and less panicked.
The only thing I read about why Dutch gov websites "went down" was as a precautionary measure against this exploit (awaiting the patch), not because they actually got hacked.
Can you link any reports about any site being afflicted by this exploit? (Dutch government website, or other)
The parent comment is implying PHP servers arent at risk, because default nginx limits requests to 1mb. I'm saying that is a bad argument, and a lot of real websites that went offline voluntarily, like the dutch gov, would have endpoints that accept >1mb requests.
Putting https://stealmybitcoin.com/ behind a default nginx proxy and giving it no features is a toy PR stunt hoping to salvage PHP's reputation.
