Google awarded a record $250,000 bounty to researcher "Micky" for discovering a critical Remote Code Execution (RCE) flaw in Chrome’s IPCZ transport system, which allowed complete sandbox escape. The exploit abused Chrome’s IPC mechanisms to impersonate privileged processes and duplicate high-privilege handles, enabling arbitrary code execution. Google patched the issue in Chrome versions M136 and M137, praising the bug’s complexity and the researcher’s high-quality submission.
