HighCVSS 7.5
Summary
A security firm, XBOW, used OpenAI's GPT-5.6 AI model to build a $250,000 Chrome full-chain exploit in just six days. Google has since fixed the bugs, and the exploit was the first full-chain reward under the 2026 Chrome Vulnerability Reward Program and the first to an autonomous security company. The company estimates that before the fixes, approximately 1 billion Chrome users on Windows were at risk.
