Published Dec 29, 2023 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
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.

Remediation

Vendor Workaround

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.
