CVE-2026-56301Nuxt - Arbitrary File Read via World-Connectable vite-node IPC Socket on Linux

Description

Nuxt 4.0.0 before 4.4.7 and 3.18.0 before 3.21.7, when running the development server (nuxt dev) on Linux, binds the vite-node IPC server to an abstract-namespace Unix socket without permission restrictions, allowing local users to enumerate and connect. Unprivileged co-resident users can exploit the unprotected module request handler to read arbitrary files such as .env and SSH keys through the SSR plugin pipeline. Production builds are unaffected, as the IPC server runs only in development.
