OpenAI ambulance chasing the PHP vulnerabilities and pretending they found and disclosed them (they did not) is disgusting. It’s a media play and it’s really gross, and says a lot about OpenAI.
Regarding the rumours the PHP patches don’t fix the vulnerabilities - it’s not true, they patch the vulnerabilities of issue.
There’s a separate issue which people are mixing up. Don’t panic about that one.
If you use Palo-Alto firewalls, make sure you upgrade for the PHP vulns.
In particular, if you have the mgmt interface facing the internet upgrade those now. The Palo-Alto firewall VMs have ASLR disabled which makes exploitation trivial.
Also update Citrix Netscaler boxes for PHP vuln, particularly if you have mgmt interface facing Internet. Why? You guessed it - ASLR is disabled.
Also hp system management homepage (installed on HPE Proliant servers) all ship with PHP.. with no ASLR. There doesn’t appear to be a patch for that, you can use it to surf around flat networks as it drops you as SYSTEM/root.
There’s absolutely shit tons of exploits for PHP2Shell on GitHub and basically none of them actually work to RCE as nobody can figure out ASLR properly.
Which is good, because patching is going to take a long time.

If you’re wondering why your million dollar cybersecurity vendor appliances don’t have ASLR enabled.
ASLR supporting PHP exploits are coming, probably next week.. but it’s a really good security control (from decades ago) you should demand your vendors actually enable as it enabled time for orgs paying attention to patch.
The cybersecurity vendor industry itself is essentially negligent when it comes to this stuff. https://infosec.exchange/@catc0n/117487878549556020
There is another PHP potential RCE vulnerability - CVE-2026-115560 - without a patch. Do not panic.
It is a non-default configuration and will not be a widespread issue.
The mitigations in this thread already fix it, if you want to panic.
PHP Foundation’s budget is about 700k a year. It’s used on something like 40 million websites. Almost no company who uses it contributes anything and many people work on it for free.
The latest trend is cybersecurity and AI vendors have realised they can vampire off its security for publicity (money).
Perhaps the world would be a better place if those orgs who rely on it just contributed sponsorship to the foundation, and vendors didn’t monetise vulnerabilities for themselves.
@GossiTheDog
Sure, but they knew about this since 2024!
So the main issue still is bad judgment on security here, as they invested their time and money obviously on other issues since then…
@MarkusStoll I hate to alarm you but there are likely other known, bigger issues. They need funding.
@GossiTheDog
I strongly doubt that there was a bigger issue than this, as this makes it very clear to everyone that you should avoid using PHP.
Still I concur, that whoever uses it, should contribute to this…
