{"id":"CVE-2026-119200","state":"PUBLISHED","title":"Nuxt: Dot segments in the request path bypass `server/middleware` path checks and server route rules on page routes","description":"Nuxt is an open-source web development framework for Vue.js. From 4.6.0 until 4.6.3, Nuxt resolves literal or percent-encoded dot segments before rendering a page while Nitro routing, server/middleware checks, and server route rules evaluate the unresolved path. A request such as /%2e/admin can therefore render app/pages/admin.vue and its server-rendered data while checks keyed to /admin, redirects, or per-route security headers do not apply. API handlers, appMiddleware, Nuxt 3, and Nuxt 4.0.0 through 4.5.x are not affected, and exploitation requires a client that sends dot segments without browser normalization.
