Description

A critical unauthenticated Remote Code Execution (RCE) vulnerability exists in React Server
Components (RSC) Flight protocol. The vulnerability allows attackers to achieve prototype
pollution during deserialization of RSC payloads by sending specially crafted multipart
requests with "__proto__", "constructor", or "prototype" as module names.

This module supports multiple vulnerable frameworks including Next.js and Waku.
