nodejs: Nodejs network segmentation bypass

A flaw in Node.js's permission model allows Unix Domain Socket UDS connections to bypass network restrictions when --permission is enabled. Even without --allow-net, attacker-controlled inputs such as URLs or socketPath options can connect to arbitrary local sockets via net, tls, or undici/fetch...

A flaw in Node.js Permission Model network enforcement leaves Unix Domain Socket UDS server operations without the required permission checks, while all comparable network paths correctly enforce them. As a result, code running under --permission without --allow-net can create and expose local IP...
