This repository contains a full exploit for CVE-2019-13764, a vulnerability in the V8 JavaScript engine (version 8.0.0) used in Chrome and other projects. The exploit is implemented in a single JavaScript file (CVE-2019-13764.js) and is designed to achieve arbitrary code execution on Linux Ubuntu 18.04 systems running the vulnerable V8 version. The exploit leverages a type confusion bug to gain arbitrary read/write primitives, constructs a WebAssembly module to obtain a RWX memory page, and injects shellcode that spawns a bash shell. The payload is a standard execve('/bin//sh') shellcode. The README provides context, usage information, and a link to a detailed blog post. No network or file system endpoints are hardcoded in the exploit; it is a local, browser-based attack targeting the V8 engine.
