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

• Severity: medium (CVSS 5.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-06-23 · updated 2026-06-25
• Weakness: CWE-276

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.

Affected products

• nuxt: from 3.18.0 before 3.21.7; from 4.0.0 before 4.4.7 — fixed in 3.21.7, 4.4.7

How to fix

Upgrade to a fixed version: nuxt 3.21.7, 4.4.7. Check the vendor advisory for mitigations.
