OpenAI's AI Models Help Researchers Discover Critical PHP Vulnerabilities in "Patch the Planet" Initiative

OpenAI says researcher Calif identified a critical PHP flaw using GPT-5.6 Sol, while Wiz independently discovered and reported both vulnerabilities. PHP maintainers led the fixes, with OpenAI and partners preparing protections ahead of disclosure. OpenAI estimates PHP runs 70% of websites and says that, to its knowledge, AI found the vulnerabilities before attackers, giving defenders time to prepare.
