Nuxt is an open-source web development framework for Vue.js. From versions 3.11.0 to before 3.21.7 and 4.0.0 to before 4.4.7, there is a route-rule middleware bypass via case-sensitivity mismatch between vue-router and the routeRules matcher. This issue has been patched in versions 3.21.7 and 4.4.7.

 https://cve.radiocsirt.org/vuln/ghsa-mm7m-92g8-7m47 GHSA-mm7m-92g8-7m47 — Nuxt: Route-rule middleware bypass via case-sensitivity mismatch between vue-router and the routeRules matcher 2026-10-08T04:26:58.607304+00:00

Affected: npm: nuxt

## Impact

Nuxt looks up `routeRules` for the current navigation by calling `getRouteRules({ path: to.path })` from the page-router plugin and the no-pages router plugin. The compiled `routeRules` matcher (built on `rou3`) performs case-sensitive matching, while vue-router is configured with its default `sensitive: false` and matches paths case-insensitively.

The two routers therefore disagree on which rules apply to a given request path: vue-router still matches the page record for `/Admin/dashboard`, but the `routeRules` lookup for the same path returns no match. Any `appMiddleware` declared via `routeRules` is never added to the middleware set and never runs, on both SSR and client navigations. The same path skips other path-keyed route rules in the same way (`ssr`, `redirect`, `appLayout`, and the prerender / payload hints used client-side).

For applications using `routeRules` with `appMiddleware` as an authorization gate (a documented pattern), an attacker can flip the case of any static segment in a protected URL (for example `/Admin/dashboard` instead of `/admin/dashboard`) to render the protected page with the middleware skipped. The server returns the fully server-rendered page including any `useFetch` / `useAsyncData` results captured during SSR.

This is an instance of CWE-178 (Improper Handling of Case Sensitivity) leading to CWE-863 (Incorrect Authorization) for apps that treat `appMiddleware` as an authorization boundary.
