Part 6/10:
While both React and Next.js are affected, Next.js faces a higher risk level because of its default behavior. React by default requires developers to opt-in to server rendering features, so vulnerabilities in server components are not enabled globally. Conversely, Next.js defaults to server rendering for many components in a new project, meaning that many applications are naturally susceptible without configuration changes.
In the demonstrated case, a default Next.js installation was vulnerable immediately after setup. This highlights how easily this flaw can be exploited in real-world scenarios, especially in applications that haven't been patched or configured securely.
