Hey folks, wanted to swing back here with an update. After digging through many different issues and discussions, I've made a new page in the documentation (PR) specifically for Content Security Policy and nonces. This docs page:

• Explains how to generate a nonce with Middleware
• Shows how to consume the nonce in a route with headers()
• Shows a complete CSP without needing to use any unsafe
• Shows how to ignore the nonce Middleware from running on prefetches / static assets

Further, we've patched some bugs and made improvements to nonce handling in Next.js that will be available in the latest canary version (for those of you time traveling from the future, upgrade to Next.js 13.5). We also updated the with-strict-csp example in the examples/ folder, which is backlinked from the new documentation page.

Really hope this helps out, thank you all 🙏 I'll be closing this discussion out. To continue the discussion, please go here.
