CVE-2026-119200Nuxt: Dot segments in the request path bypass `server/middleware` path checks and server route rules on page routes
Medium 6.5
In plain English
A medium-severity incorrect authorization in nitro-server from @nuxt. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 27% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official 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. This issue is fixed in version 4.6.3.
