Link to the code that reproduces this issue

https://github.com/MTroian94/next-version-window

To Reproduce

1. Build the application (pnpm run build)
2. Start the production server (pnpm run start)
3. Open the browser and visit the page
4. Open the browser console
5. window.next shows the actual version

Current vs. Expected behavior

Following the steps from the previous section, I expected to see the next version in window.next

Additional context

These discussions:

• How to hide next.js version from tools like Wappanalyzer #68058
• How to remove nextjs version information #39488

show how to hide the Next.js version by modifying the built code. Is it possible to hide the Next.js version using the configuration in the next.config.js file? Setting poweredByHeader to false is not enough.

This is still a potential security issue for apps using Next.js, as attackers can see which Next.js version is used and potentially find exploits for that particular version.

Thank you!
