 As a professional web developer focusing on arcane uses of Django for arcane purposes, it occurred to me a little while ago that I didn't actually know how a web framework _worked_.
 
 So I built one.

 ```
 
+> [!DANGER]
+> The CSRFMiddleware is incomplete at best and dangerous at worst. I am not a security expert, and my implementation is [very susceptible to the thing it is meant to prevent](https://en.wikipedia.org/wiki/Cross-site_request_forgery). While this is an big issue (and moderately hilarious), the middleware is still provided to you in its unfinished state. Be aware.
+
 Cross-site request forgery, put simply, is a method for attackers to make legitimate-looking requests in your name to a service or system that you've previously authenticated to. Ways that we can protect against this involve aggressively expiring session cookies, special IDs for forms that are keyed to a specific user, and more.
