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

• npm @hono/node-server: >= 1.3.0, < 1.10.1 → fixed in 1.10.1

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. (/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 Workarounds Nothing.
