Security Impact
CVSS: 5.3
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
How to Fix CVE-2024-23340
To remediate this vulnerability, upgrade all affected @hono/node server dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install @hono/node-server@1.4.1Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls @hono/node-serverHow to Check if You Are Affected
To determine whether your Node.js application is affected by CVE-2024-23340, inspect your project dependencies using npm:
npm ls @hono/node-serverAnalyze the terminal output to locate any version of @hono/node server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.1), your application is affected.
Note: The npm ls @hono/node-server command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In @hono/node server, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\n\nSince v1.3.0, we use our own Request object. This is great, but the `url` behavior is unexpected.\n\nIn the standard API, if the URL contains `..`, here called \"double dots\", the URL string returned by Request will be in the resolved path.\n\n```ts\nconst req = new Request('http://localhost/static/../foo.txt') // Web-standards\nconsole.log(req.url) // http://localhost/foo.txt\n```\n\nHowever, the `url` in our Request does not resolve double dots, so `http://localhost/static/.. /foo.txt` is returned.\n\n```ts\nconst req = new Request('http://localhost/static/../foo.txt')\nconsole.log(req.url) // http://localhost/static/../foo.txt\n```\n\nIt will pass unresolved paths to the web application. This causes vulnerabilities like #123 when using `serveStatic`.\n\nNote: Modern web browsers and a latest `curl` command resolve double dots on the client side, so it does not affect you if the user uses them. However, problems may occur if accessed by a client that does not resolve them.\n\n### Patches\n\n\"v1.4.1\" includes the change to fix this issue.\n\n### Workarounds\n\nDon't use `serveStatic`.\n\n",
