Miniflare vulnerable to Server-Side Request Forgery (SSRF)

High severity GitHub Reviewed Published Dec 29, 2023 in cloudflare/workers-sdk • Updated Dec 29, 2023

Package

npm miniflare (npm)

Affected versions

>= 3.20230821.0, < 3.20231030.2

Patched versions

3.20231030.2

Description

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 [email protected].

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.
