Somebody has leaked CVE-2026-109618 and CVE-2026-109619 in PHP before the patch is out.

@piggo @GossiTheDog Don't worry, the first to break in will usually patch it for you.
@yngmar @GossiTheDog well I'll just watch it from the back seat here. But there is no infrastructure for automated updates, so the servers will sit unpatched for days at least
-
A really good mitigation for this btw - AppArmor or SELinux.
Google something like apparmor restrict php from executing commands. Works against these CVEs.
Sucks for cybersecurity vendors who shipped their appliances using PHP without SELinux or AppArmor, of course.
@GossiTheDog Happily, we do have apparmor already running, so thanks for the mini profile.
(I also have an alarm set up for a Fuck You Assholes three hour early wakeup to stagger over to a console in time for the patch drops. But, well.)

Somebody has posted technical details of the PHP vulns. It’s likely LLM generated from GitHub commits (or somewhere!) but it’s in the right ballpark on one of the issues.
There’s also another decent mitigation in this but the only real one is to patch.

@GossiTheDog thank you that was the best explanation of it yet

The PHP situation will lead to a mass of incidents - it’s one of the biggest vulns in years.
Shodan dork "X-Powered-By: PHP/" - a lot are on EOL versions with no patch. It’s also more hosts as not everybody lists their PHP version in headers.

@GossiTheDog yeah, I'm calling bs on this too. From a place of "having tried the poc", see e-mail for details.

@GossiTheDog This is LLM-written (evidence for claim: A - the entire text flags 100% in Pangram, which anecdotally is not perfect but is pretty good. B. the credited author ( https://x.com/J4ck3LSyN ) sounds nothing like this on their Twitter and people don't change their voice so easily)
I don't say this to entirely disparage it - lots of hackers do this currently to put their conclusions in "nice" writing, and the conclusions might be right. But I'd be careful if you can't follow the claims.

That's only because of the Mercator projection -

I think PHP probably has to bring forward the release as cyber vendors who have advanced notice told customers details so now everybody is running around with details.
There’s probably a conversation to be had about cyber vendors effectively reselling open-source project intelligence for profit. I don’t think it is great. Protecting the ivory tower sucks.

@spacefinner @GossiTheDog thank you for noticing that and flagging it! I agree, and I really wish every vuln disclosure wasn't written like this now :?

@GossiTheDog All the the Docker containers that are only updated with every application release will also have a fun time
