National Security Agency’s sent out an alarming warning on Wednesday that two critical holes had been found in PHP, with patches already issued by the PHP Foundation . PHP is a server-side programming language so widely used for web applications that it powers roughly 70% of the websites on the internet; by some accounts, that’s more than 33 million sites . Separately, the Wiz team also used AI, namely its Wiz Atlas security AI agent, Gemini 4 Argon, and GPT-5.6 Sol to find multiple vulnerabilities in PHP. Both OpenAI and Wiz followed responsible security research practices and worked with PHP on patches before publicly disclosing the flaws.

PHP is a server-side programming language so widely used for web applications that it powers roughly 70% of the websites on the internet; by some accounts, that’s more than 33 million sites . It is also used by popular content management systems like WordPress.
The NSA warned that these holes are so severe that if a website can’t be patched immediately, it should be pulled off the web until it can be. The holes allow attackers to infiltrate the server’s file system or a database that may be used by the web app.
Interestingly, these holes have been tucked away in all versions of PHP since version 5, which was released in 2004. Websites not running relatively current versions of PHP will have some updating work to do, as PHP 8.1 and older versions are no longer supported. The recommendation is to update the web server to the current version of PHP, which is 8.5.12.
So how did two such ubiquitous, decades-old flaws that affect nearly every website on the internet suddenly come to light? AI, naturally, particularly via OpenAI and Google’s Wiz.
Security testing company Calif was engaged in OpenAI’s “Patch the Planet” initiative to find flaws in open source software. Using GPT‑5.6 Sol, it found one of the flaws, OpenAI disclosed in a blog post . Separately, the Wiz team also used AI, namely its Wiz Atlas security AI agent, Gemini 4 Argon, and GPT-5.6 Sol to find multiple vulnerabilities in PHP.
This is the kind of security issue that was found and prevented by AI, but is also a high risk because of AI Reported by TechCrunch AI on October 21, 2026.
