1. session.upload_progress.enabled = Off, in php.ini and as php_admin_flag in every FPM pool, so per-directory config can't turn it back on. It's one of the two confirmed consumers in GHSA-6wmf, and the validated FPM path depends on it. Almost nobody uses it, and the advisory suggests leaving it off even after patching.
2. Refuse multipart request bodies at the web server, before PHP parses them. All of the GHSA-w8hw out-of-memory strategies go through multipart parsing. On Apache it's a rewrite rule matching a Content-Type of multipart/form-data that returns 403. On Caddy it's a header matcher that responds 403. The cost: every browser upload breaks (media library, plugin zips, importers). Check your public forms first.
3. Check your SAPI. Both bugs have confirmed RCE against mod_php. FPM is narrower: the validated path needs upload_progress, and the early INI consumer only applies if your front end sends PHP_VALUE/PHP_ADMIN_VALUE. To check, grep your Apache, nginx and Caddy configs for it, and run apache2ctl -M | grep php.
4. pm.max_requests = 1 in the pools. A worker serves one request and exits, which breaks the stale-state chain: the "producer" and "consumer" requests must land on the same worker. It costs a fork per request.
5. Lower max_input_nesting_level and post_max_size, per the advisory.
6. Housekeeping that should already be done: no .php served from uploads directories, and remove any stray phpinfo.php. Scanners request it constantly, and it tells an attacker your exact build.
The fact is you had no idea how useful or dangerous your advice was. PHP maintainers said to shut it down, how many people followed your advice instead? Did it work or just leave them vulnerable? Do you know?
Because you're heavily implying that the people who knew about the details of the vulnerability were panicking and thank god we had you with an LLM

What everyone is looking for.
I assume it just got pushed?

Glorious. Today of all days it would genuinely give me pause for caution.
edit: yeah, really not feeling that: https://github.com/php/php-src/compare/php-8.2.34..php-8.2.3...
Hopefully just a mistake? But looks like a botched release at the least
Is it perhaps a bit misleading, and only means that there's no branch containing that commit?

awake2death or something
Is this even reachable on Linux due to overcommit? Maybe by attempting a single extremely large allocation?

https://github.com/Qbix/proxy -- open source MIT licensed, I made github actions compile it as a Cosmopolitan binary so it can work across many operating systems (thanks Justine)
I wrote it so I could deploy it myself on our old nginx + php-fpm setups, thought I would share. It should work with all top servers (nginx, apache, caddy etc)
It's free and MIT licensed, open source and it is currently the only alternative to patching your PHP. The "profit" is for people who don't get PWNED today!!!
Many people can't patch your PHP. If you can't be bothered to even look at the repo, you may want to sit this one out.
Going to migrate the box to Debian in-place. (Or Gentoo, the way things are currently going.)
It feels like many times PRs could just be that.
"I'm not a real programmer. I throw together things until it works then I move on. The real programmers will say 'Yeah it works but you're leaking memory everywhere. Perhaps we should fix that.' I’ll just restart Apache every 10 requests." -Rasmus Lerdorf
By simply searching for websites that used local includes to load other pages, you could get RCE.
At this point, running webapps in JS workers/sandboxes sounds like a good idea. Vendors take care of patching.
Then your own comment would not be such low effort and useless human slop.
Do you agree or disagree with the comment's claims? Did YOU verify anything? Let's all hear you fact check and proofread and reword what it said so it matches your standards, instead of just listening to you bitch and complain without offering any useful information.
Or do you not actually know anything about PHP administration, programming, and security, so you're only capable of information-free drive-by anti-ai posts, without any other useful content or corrections?
Ball's in your court.
And they botched this as someone talked. To me this looks like they used this for a PR stunt and aimed for an RCE.
Edit: was looking Wiz post when citation was from OpenAI
The launchpad server is throwing 503 errors all over the place, so that's probably the reason for the delay. Sury's own repo has the fixes all right.
I’d press go too - if something this big was known to some but not all…
We’ll all get through together
On the other hand, I don't mind AI companies doing this sort of thing, I'm sure a lot of our internet infrastructure could benefit from these sorts of fixes and changes.
August 24, 2026: Wiz Research reports the vulnerabilities to the PHP security team.
September 21, 2026: PHP acknowledges the reports and begins developing a coordinated fix.
The official interim fix for php8.5 [1] could have been published 24h ago, or even 2 weeks ago, without revealing any security details. Specifically once the POC came online. Would have been significantly more useful than these polished blogs.
Perhaps I'm missing something here, but the costs (dev/sre time, missed sales, potential data leaks and hacks) of the way that this was handled is significant.
[1] https://github.com/php/php-src/security/advisories/GHSA-6wmf...
these security companies reported it 2 months ago. it took a month for the php security team to acknowledge it and another month for the php team to develop & release the patch.
if you're going to be upset at anyone it should not be the reporters.
>The official interim fix for php8.5 [1] could have been published 24h ago, or even 2 weeks ago, without revealing any security details.
publishing the fix = publishing the security details.
If I had details on a RCE like this I'd report it but if I got no response for a WEEK I'd be trying other venues.
i highly doubt it. these are pretty big names in the security sector who have plenty of experience reporting high severity vulns.
We don’t know when it went from a “memory safety issue” to “php2shell/RCE”.
Calif’s report is a little light on timelines, but reading between the lines, it seems they took a while to turn this into an actually exploitable vulnerability.
Finally, at least pre-LLM (and maybe a bit outdated now), responsible security disclosure norms is that you usually do wait for vendor (up to 90d) if there’s no signs of active exploitation. Even if it’s a RCE. Actually, especially if it’s a RCE.
The last thing you wanna do is go pinging random non-security PHP contributors or maintainers and have it leak with zero patch. That is truly the worst outcome.
Yes, this is bad, but also, it’s apparently been bad for decades; and it could’ve been much worse.
Sure, it’s PHP, but plenty of companies or organisations might have some PHP running somewhere; and once you’re in, lateral movement becomes a lot easier.
Whether keeping the update quiet and including it in the next normal release, where there are more trees obscuring the wood that is the security concern, and announcing the bug a short time later once anyone using distro updates or otherwise keeping on top of things have updated, would be safer overall than what has happened today is up for debate. I can think of arguments in both directions.
--------
[1] which does have a slight whiff of AI marketing about it - would a human-found issue, without the option of a big AI company to claim some credit, have been handled differently?
Boy, do I hate these PR websites masquerading as vulnerability reports. It's slop all the way down with these companies.
It's like slop for infosec markters
UPDATE: Just going to ship a Linux binary for now, that's where most hosting is. Almost no one hosts from a MacOS or Windows machine. The Cosmo binary was overkill here.
