OpenAI Launches Global Cybersecurity Coalition After AI Uncovers Critical PHP Flaws Affecting 70% of Websites

OpenAI announced an international vulnerability-response initiative called Patch the Planet following the discovery of critical security flaws in PHP, the programming language powering an estimated 70% of websites worldwide. The vulnerabilities, tracked as CVE-2026-109618 and CVE-2026-109619 and collectively termed "php2shell," had persisted undetected in PHP for 14 years before AI-assisted security research identified them in August 2026.
