OpenAI says its models helped find a critical PHP flaw, and there's a Codex skill to check your site

OpenAI says its models, working within its 'Patch the Planet' programme, helped researchers find serious security flaws in PHP, the language behind an estimated 70% of websites, and that it spent two months with PHP's maintainers and security firms preparing a fix that needed a major change to PHP itself. It calls this one of the most impactful vulnerabilities in recent memory (its own assessment), says every PHP site can now upgrade safely, and has published a Codex skill you can point Codex at to check whether your site is affected.

Why it mattersIf your website runs on WordPress or anything else built on PHP, ask your host or developer today whether PHP has been upgraded and the recommended protections applied. Managed hosts often handle this for you, but check rather than assume.
