AI just found a bug that’s been hiding for over 10 years in the code that powers 70% of the internet
are we ready for a world where AI finds vulnerabilities faster than we can fix them?
does this excite you… or scare you a little?
OpenAI models helped researchers—operating as part of our Patch the Planet initiative—discover critical security flaws in PHP, an open-source programming language used to run an estimated 70% of websites.
Over the past two months, we led a coalition of maintainers, researchers, and security providers to prepare fixes and protections ahead of disclosure. This duration was necessary because the fix was quite intricate and required a major change to the PHP engine. Every site using PHP can now safely upgrade their version to stay secure, in addition to applying mitigations from various security vendors.
Due to the severity of these flaws and PHP’s widespread use, we consider this bug to be one of the most impactful vulnerabilities in recent memory. It also marks a new phase, where AI can find security bugs with internet-scale impact.
This is an example of the Defender’s Window in action: to our knowledge, frontier AI was able to find this vulnerability ahead of attackers, giving defenders time to prepare.

OpenAI may claim a role in the coordinated response and patching process. But the initial discovery and exploit development, however, occurred several months earlier by an independent researcher.

This meme aged interestingly.
We were told AI would build software on unstable foundations. Now AI-assisted researchers are exposing critical flaws in PHP, part of the foundation we were already standing on.
Maybe “human-written” was never the security guarantee.

Former DOE security engineer @asynchronous_x explains how a miscommunication turned a planned PHP2Shell fix into a race against hackers:
"It should have been the best-case scenario. Security researchers identified these vulnerabilities, developed proof of concept exploits in advance, and were informing the PHP core team for fixes. That whole part was working fine."
"The reason this one’s unique is there was basically a leak of the vulnerability before the disclosure. That was supposed to be released on October 22nd, today. Unfortunately, there was a miscommunication, and they released some of the details early. So there was this panic race where the problem is out in the wild, but we don’t have a fix prepared yet."
"The thing it’s taught the security realm is that we probably can’t rely on coordinated disclosure anymore. If the speed at which people can develop exploits is now so fast that we can’t possibly rely on things not getting leaked, then it’s not something we can lean on as much as we used to."

AI finding bugs is one thing.
finding a critical vulnerability in PHP, a language powering around 70% of websites, is a different level.
OpenAI models helped researchers uncover these flaws, giving maintainers time to prepare fixes before disclosure.
the part that stands out to me is the Defender’s Window.
AI isn’t just making attacks easier. it can also help defenders find weaknesses before attackers do.
the race between finding vulnerabilities and exploiting them is changing.

If your website, online ordering, or loyalty vendors run on PHP, ask them whether they've patched yet. AI is now finding bugs faster than most of us patch them, so vendor patch speed belongs in every tech review.
