@hono/node-server can't handle "double dots" in URL

CVE-2024-23340

Description

@hono/node-server is an adapter that allows users to run Hono applications on Node.js. Since v1.3.0, @hono/node-server has used its own Request object with url behavior that is unexpected. In the standard API, if the URL contains .., here called "double dots", the URL string returned by Request will be in the resolved path. However, the url in @hono/node-server's Request as does not resolve double dots, so http://localhost/static/.. /foo.txt is returned. This causes vulnerabilities when using serveStatic. Modern web browsers and a latest curl command resolve double dots on the client side, so this issue doesn't affect those using either of those tools. However, problems may occur if accessed by a client that does not resolve them. Version 1.4.1 includes the change to fix this issue. As a workaround, don't use serveStatic.
