OpenAPI specifies that each *path operation* requires a response description.

So, if you don't provide one, **FastAPI** will automatically generate one of "Successful response".

issue (DoS, authentication bypass, information disclose, ...) and the assumptions you're making (e.g. do
you need access credentials for a successful exploit).
