CVSS 3.1
8.1 highCVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:NCVE-2023-7078
High (8.1) in cloudflare miniflare. EPSS 0.6% chance of exploitation in the next 30 days. Fixed in miniflare 3.20231030.2.
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.
