This repository contains a proof-of-concept exploit for CVE-2023-4427, a vulnerability in the V8 JavaScript engine used by Google Chrome (tested on version 117.0.5938.62 for Linux). The exploit is implemented as a JavaScript payload in 'exp.html', which uses advanced heap manipulation, object property enumeration, and WebAssembly to achieve arbitrary code execution in the browser's renderer process. The 'main.html' file demonstrates how to load the exploit in an iframe from a different domain (e.g., http://a2.com:8008/exp.html), which is necessary to brute-force ASLR protections. The README provides context, usage notes, and references the original vulnerability report. The exploit is unstable and requires either ASLR to be disabled or multiple domains to increase reliability. No hardcoded IPs or domains are present except for the example 'a2.com', which is meant to be configured by the user. The repository is structured for CTF or research use and does not include weaponized or automated payload delivery.
