@hono/node-server has Denial of Service risk when receiving Host header that cannot be parsed
Impact
The application hangs when receiving a Host header with a value that @hono/node-server can't handle well. Invalid values are those that cannot be parsed by the URL as a hostname such as an empty string, slashes /, and other strings.
For example, if you have a simple application:
import { serve } from '@hono/node-server'
import { Hono } from 'hono'
const app = new Hono()
app.get('/', (c) => c.text('Hello'))
serve(app)Sending a request with a Host header with an empty value to it:
curl localhost:3000/ -H "Host: "The results:
node:internal/url:775
this.#updateContext(bindingUrl.parse(input, base));
^
