Researcher Uses Claude Opus to Build a Working Chrome Exploit Chain

A researcher used an AI model (Claude Opus) to develop a chained exploit targeting Google Chrome's V8 engine (CVE-2026-5873 plus a WasmCPT UAF sandbox bypass) to achieve remote code execution against an outdated Chromium build embedded in the Discord desktop app; the experiment illustrates how AI-assisted exploitation can produce high-impact exploits for Electron-based apps that lag upstream patches, though it required heavy human oversight and consumed substantial time and tokens.
