> On October 21st at 07:41 UTC, more than six hours before the coordinated release, Chainguard unilaterally broke the embargo and published built images containing the fix.
This is incredibly damming of Chainguard. I struggle to see justification for this, even with the chaos approaching the coordinated release.
They (is it the CEO?) commented on it earlier here: https://news.ycombinator.com/item?id=50176735
In their place I would worry that this was the last time anyone shared an embargoed build with them.
Let's hope so. Shall we create a new norm? A 365 day timeout, for companies like Chainguard that deliberately break embargoes.
Very irresponsible behaviour in my opinion; and if it's a decision made unilaterally by their CEO, probably a breach of their SOC 2 certification. What's next? "$X isn't patching this CVE fast enough, here's a binary blob of our fix, don't worry, we're making this free!"
Nah, Chainguard should be praised for this. It was a different company that leaked the POC early, and then PHP, Wiz, OpenAI, and Calif sat on their hands doing nothing while the vuln was being actively exploited in the wild. Chainguard did the right thing by getting the fix out as quick as possible to stop the bleeding (or gushing flow of blood, really) rather than sitting on it so they could make a coordinated marketing post, like the others did.

I think multiple companies didn't respect the embargo, in different ways.
That can be for marketing purposes or by mistake. Not sure how to deal with that.

I dunno, the post is awfully critical of Chainguard for leaking a fixed binary 6 hours early, but it was the research firm "partner" that "mistakenly" posted the dancing anime POC video over 24 hours early that created the mass panic (not to mention spawning millions of agents crawling the php codebase and trying to brute force a POC and probably using more energy than a lot of countries in the process).
i keep seeing mentions of the video, but is it still available anywhere?

Song is Petite Meller - High Forever (Marlon Hoffstadt Remix). Which is annoyingly catchy

Agree. If I'm following along correctly, it seems Calif is really the one to blame not Chaingaurd.
Both are to blame.
Calif more than Chainguard, but still Chainguard too.
Calif was obviously twitching to claim credit for their findings, and what I find troubling is this eagerness was more important to them than giving users a chance to update their systems.
Even if they ended up waiting only a day post release I would still say it seems a bit too soon. Maybe a week after. Not everyone’s system have aggressive patching schedules and PHP is soo heavily used.

The video has no usable details in it.
It's maybe not professional to release an omg panic video, but not even remotely the same thing as what chainguard did.
I don't know, it's showing most sites being pwnd in less than 20s with some taking just under 30s. Of course, that's on homeboy's local Mac. Not sure how long it takes to gain control with PHP2Shell to run the exploit though. Just started looking at that part myself

there were security guys publishing inferred details from [INFO] messages, it did contain more than zero usable details

They took it down but someone (Kirill Firsov: https://x.com/k_firsov/status/2112641845926989944) added the anime stuff and reposted it. Totally irresponsible.
Edit: okay he didn't add the anime, but he reposted it.
The company, Calif, has it with the music, effects and Ui Shigure animation on their own website and youtube channel: https://calif.io/php2shell/#php-5-4-0-rce

I kinda get Chainguard's position here. They were part of the embargo, saw exploits hitting in the wild already and decided to release rather than hold things back.
Embargos make sense if no one is exploiting it yet, but if its out in the wild, the best path forward is releaseing as soon as possible.
Did they actually see exploits in the wild? The PHP Foundation team disputes this, and say they didn't observe any working PoC capable of an exploit.
The person who wrote the widely-referred-to tweet last night (claiming to "have recreated & lab/field tested CVE-2026-109618 / CVE-2026-109619") followed up a couple hours later and said that their POC had not been proven to work "in the wild"

Cloudflare's blog post announcing its updated WAF rules directly implies the existence of in-the-wild exploits: https://blog.cloudflare.com/php-vulnerabilities-waf-protecti...
"Cloudflare successfully deployed multiple mitigations for all its customers while the vulnerability was leaked before the official release date and we observed attack traffic targeting our customers."
If that's not an in-the-wild exploit, it literally couldn't have been further away than one or two more iterations.

Chainguard most likely interpreted Calif's dancing anime girl video as a script kiddie who had found a POC.

Many people actively following would have 403'ed multiparts so people seeing those blocked might have assumed it started being exploited early instead of probes / background noise.
This single-handedly assures that I will never, ever do business with Chainguard or any member of its C-suite executive team.
if their comment in true (linked in sibling comments), then it's really not damning. typically an embargo is ended when someone leaks early or it's being exploited in the wild.
so, if they saw evidence of exploits in the wild, it is not unusual at all to release the fix.
If they're gonna unilaterally release an exploit patch 6 hours before an agreed upon embargo for a CVSS 9.2 that affects like ~70% of the internet then they better have reams of evidence showing this was being exploited in a widespread manner and not just "we saw a dancing anime girl edit of a theoretical exploit on twitter, so we had to release it to the world"
And evidence they at least gave a heads up to everyone in on the embargo, eg "I have to release you all have 1 hour to get on board".
There is a MASSIVE difference between a small number of people exploiting in the wild, and a few hours after a release a bazillion script kiddies doing so. The move to release and break an embargo was childish, absurd, self-serving, and lacking in all common sense. Not to mention, breaking trust.
I agree with those in this thread who say, never going to do business with them. Ever.

It's the age of LLMs. Exploits go from theoretical to real fairly quickly. PHP's open source, it's not impossible to conceive of someone seeing that video, getting the general idea of what to do, and working the rest out with a decent model.
[flagged]
There were signs that others broke the embargo too. Public (this one video everyone is talking about), but maybe also non-public. There were some rumors going around which part of PHP was affected. That was enough for some people to figure out the vulnerability.
But it's also possible, that some attackers got non-public inside information.
If the embargo is already broken in a meaningful way, it suddenly becomes much less clear if it is still in place after all. Emphasis on >less clear<.
Brain rot is making us incompetent, dangerously impatient, or a mixture of both.
Not sure if this [1] comment is from them?
Because if there are already publicly available exploits seen, it makes no more sense to keep holding patches back just so that OpenAI etc. can get a nice press release

So if I'm understanding correctly:
1. There was a leak of the pre-announcement
2. Calif sees leak, goes and releases dancing anime girl video before pulling it, goes viral
3. Chainguard sees dancing anime video, doesn't recognize Calif, and thinks the exploit is in the wild
[Edit 3a]: Or alternatively, Calif's leaked video causes the PoC to be found by others by providing enough of a lead
4. Chainguard releases updated binaries thinking it doesn't matter, causing the real exploit to then be found early
5. Which then causes PHP Foundation to basically have a meltdown
Personally I blame Calif for the unprofessional video which absolutely completely looks like some script kiddie and for being too detailed [edit 2: assuming Calif produced it and the anime wasn't a prank edit]. In this case it wasn't just unprofessional fun but may have literally messed up the responsible disclosure.
> 3. Chainguard sees dancing anime video, doesn't recognize Calif, and thinks the exploit is in the wild
I'm not sure about this part. I saw https://jackalsyn.com/posts/php-up-2026.html going around a bit over 12 hours ago, before the chainguard images went out, and plenty of other chatter of exploitation happening in the wild.

Or maybe the anime girl video was an edit someone else made on top of an otherwise normal Calif video.
Still not great though.
2 replies →
Not really sure if 3 is correct. Might have been Calif leaks the video -> it goes viral -> people make PoCs based on the video -> Chainguard releases the binary because there seem to be credible PoCs out there (that are not just the Shigure Ui video).
