There was a problem hiding this comment.
Would it make sense to default to a node based payload for the highest chance of success on arbitrary targets? 🤔
i.e. we won't know if the target has curl or wget - but I imagine it'll have node on the path by default? 👀

Vulnerability Details
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.
