CVE-2021-38001 is a type confusion vulnerability in the V8 JavaScript engine in Google Chrome prior to version 95.0.4638.69. The flaw allows a remote attacker to exploit heap corruption by enticing a user to visit a specially crafted HTML page. Successful exploitation can lead to arbitrary code execution within the context of the browser process.

This repository is a proof-of-concept (POC) exploit for CVE-2021-38001, a vulnerability in the V8 JavaScript engine used by Google Chrome. The repository contains two JavaScript module files (1.mjs and 2.mjs) and a README.md. The main exploit logic is in 2.mjs, which imports a function from 1.mjs, defines a class, and manipulates the prototype chain in a loop, calling the imported function. This is designed to trigger the vulnerability in V8 when run with the d8 shell (the standalone V8 JavaScript engine). There are no network endpoints or external targets; the exploit is purely local and demonstrates the bug in a controlled environment. The code does not provide a shell or further payload, and serves as a minimal POC for researchers or developers to reproduce the issue.

The main exploit logic is in 2.mjs, which imports a function from 1.mjs, defines a class, and then manipulates the prototype chain of the class in a loop, calling the imported function. This is designed to trigger the vulnerability in a vulnerable version of V8. The README provides instructions to run the PoC using the d8 shell. There are no network endpoints or external targets; the exploit is purely local and intended for research or demonstration purposes. No weaponized payload is included, and the code does not provide post-exploitation capabilities.
