How to Fix CVE-2023-7078

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

miniflare fixed: 3.20231030.2 
npm install miniflare@3.20231030.2
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 miniflare

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2023-7078, inspect your project dependencies using npm:

npm ls miniflare

Analyze the terminal output to locate any version of Miniflare in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.20231030.2), your application is affected.

Note: The npm ls miniflare 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-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Miniflare, 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

### Impact Sending specially crafted HTTP requests to Miniflare's server could result in arbitrary HTTP and WebSocket requests being sent from the server. If Miniflare was configured to listen on external network interfaces (as was the default in `wrangler` until `3.19.0`), an attacker on the local network could access other local servers. ### Patches The issue was fixed in `miniflare@3.20231030.2`. ### Workarounds Ensure Miniflare is configured to listen on just local interfaces. This is the default behaviour, but can also be configured with the `host: "127.0.0.1"` option. ### References - https://github.com/cloudflare/workers-sdk/pull/4532
