CVE-2026-56301
MediumCVSS 5.5Exploitation Probability (EPSS)
Low risk1th percentile — higher than 1% of all known CVEs
Summary
Nuxt versions 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.
Risk Assessment
Unprivileged co-resident users can exploit the unprotected module request handler to read arbitrary files such as .env and SSH keys, posing a serious threat to data security.
Recommendation
It is recommended to update Nuxt to versions 4.4.7 or 3.21.7 to secure the IPC server from unauthorized access in the development environment.
Original NVD description (English source)
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.
