OpenAI's GPT-5.6 Sol and Google's Gemini 4 Argon found critical PHP flaw affecting millions of websites

OpenAI's GPT-5.6 Sol and Google's Gemini 4 Argon found a critical PHP vulnerability that may affect millions of websites worldwide. GPT-5.6 Sol found it in the Patch-the-Planet project, and Wiz independently found the same flaw using Wiz Atlas with both models. A tool on GitHub lets server operators check whether their PHP version is affected.

Why it matters: Wiz says LLMs can adapt exploits across PHP versions, configurations and memory layouts, lowering the bar for attacks across deployments.
