GPT-5.6 Sol and Gemini 4 Argon help find critical PHP vulnerability affecting millions
OpenAI's GPT-5.6 Sol and Google's Gemini 4 Argon, alongside security firm Wiz (using Wiz Atlas), independently identified a critical PHP vulnerability; a coordinated two-month, multi-phase response involving PHP maintainers, Wiz, Cloudflare, CISA and the White House produced patches and a GitHub tool to check affected servers. Wiz says LLMs also make it easier to adapt exploits across versions and deployments, and OpenAI proposes the coordination process as a repeatable framework for future AI-driven discoveries.
