CVE-2026-119199 Details

Description

Nuxt is an open-source web development framework for Vue.js. From 3.0.0 until 4.6.3, the Nuxt development server can expose the Nitro 2 development bundle at <buildDir>/dev/index.mjs through Vite file serving when the server is reachable over HTTP. Nitro inlines private runtimeConfig values resolved at build time into that bundle, including secrets configured in nuxt.config, and Nuxt 4.6.0 and later also inline the generated development appSecret. The default localhost binding limits remote exposure, production builds and Nitro 3 are not affected, and runtime configuration supplied only through NUXT_* environment variables at server startup is not inlined. This issue is fixed in version 4.6.3.
