The adapter @hono/node-server allows you to run your Hono application on Node.js. Prior to 1.10.1, 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. The version 1.10.1 includes the fix for this issue.

GHSA-hgxw-5xg3-69jx — @hono/node-server has Denial of Service risk when receiving Host header that cannot be parsed

Affected: npm: @hono/node-server

### 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:

```ts 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)); ^

TypeError: Invalid URL at new URL (node:internal/url:775:36) at newRequest (/Users/yusuke/work/h/159/node_modules/@hono/node-server/dist/index.js:137:17) at Server.<anonymous> (/Users/yusuke/work/h/159/node_modules/@hono/node-server/dist/index.js:399:17) at Server.emit (node:events:514:28) at Server.emit (node:domain:488:12) at parserOnIncoming (node:_http_server:1143:12) at HTTPParser.parserOnHeadersComplete (node:_http_common:119:17) { code: 'ERR_INVALID_URL', input: 'http:///' } ```

### Patches

The version `1.10.1` includes the fix for this issue. But, you should use `1.11.0`, which has other fixes related to this issue. https://github.com/honojs/node-server/issues/160 https://github.com/honojs/node-server/issues/161
