Reacts biggest Mistake

A critical look at the recent wave of Next.js and React security vulnerabilities, including remote code execution, middleware proxy bypasses, XSS, and a denial-of-service bug rooted in React's server component reply parsing. The DoS exploit works by crafting a circular reference payload that causes React's parse model to loop ~53,000 times until a stack overflow, requiring no authentication. The author also questions the overall complexity and value proposition of React Server Components, arguing the architecture introduces significant attack surface for marginal developer convenience gains.
