@GossiTheDog
Looks like Calif may have a PoC called php2shell that works against WordPress. -
@GossiTheDog I had read that 8.0 and 8.1 would also be getting patches, is that not correct?
@emd @GossiTheDog Not by the PHP team, but third parties might.

Oh fun. EOD Thursday (at least in Europe).
And they couldn't release this earlier in the week because...?
(hey, at least they aren't aiming for 17:00 EDT on Friday, so let's count that as a win) -

PHP releasing patches tomorrow for CVE-2026-109618 and CVE-2026-109619
Fixed versions will be 8.5.12, 8.4.27, 8.3.36, 8.2.35
All others are end-of-life but are still vulnerable - the vulns date back to versions from 2004 onwards.
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 I may look into this, though I'm not sure how restrictive I can get with mine since I use it to host Nextcloud, which has a variety of "apps", such as one that hooks into clamd to scan files for viruses when they're uploaded, etc. I'm not certain exactly how those work and if restricting the ability to execute commands would break certain expected functionality. I need to educate myself on AppArmor anyway; seems like a good excuse to sit down and do some reading.

@GossiTheDog I’m convinced security vendors are, on average, substantially worse at security than any random vendor.

@GossiTheDog you're saying blocking your php from execve() fully mitigates this?
-

@emd @GossiTheDog If you're on an EOL version, I would suggest searching for "PHP commercial LTS".

@afilina @GossiTheDog have to see how our devops platform (Laravel Forge) will handle.
But nice to know there might be other options, thanks for making me aware of these.

@GossiTheDog https://www.behindtheconsole.com/2026/10/21/patch-your-php-pre-2026-10-20/ this shell script helps to toggle the mitigation setting to
session.upload_progress.enabled = Off -
That's gotta be the plan, right?
Force people to adopt unmaintainable slop fixes, to ensure they never will be able to get rid of that growing ball of technical debt and stay chained to the slop machines forever.

@GossiTheDog Any relation to Netscaler? There’s some php on there too. Or nothing to do with it?
-
@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

@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
