CVE-2026-119200 · Severity: medium · CVSS 6.5 · Published 2026-10-29

Nuxt is a popular Vue.js web framework used to build server-rendered web applications. Versions 4.6.0 through 4.6.2 fail to consistently normalize dot segments (like /%2e/) in request paths, allowing attackers to bypass security checks and access pages that should be restricted. An attacker can request a page with encoded dots to retrieve sensitive server-rendered content while circumventing security headers, redirects, and middleware rules that guard the legitimate path.

## How to fix

- @nuxt/nitro-server (npm): upgrade to 4.6.3 or later

  ```sh
  npm install @nuxt/nitro-server@4.6.3
  ```

- nuxt (npm): upgrade to 4.6.3 or later

  ```sh
  npm install nuxt@4.6.3
  ```


## Technical details

The vulnerability occurs because Nuxt resolves dot segments during page rendering but Nitro routing, server middleware, and route rules evaluate the unresolved path, creating a mismatch. Requests like /%2e/admin can render app/pages/admin.vue with its server-rendered data while security checks keyed to /admin do not apply. This affects Nuxt 4.6.0–4.6.2 but not earlier versions (4.5.x and below), Nuxt 3, or API handlers and appMiddleware, and requires a client that does not perform browser normalization on dot segments.

## Affected products

- Nuxt Nuxt 4.6.0 to 4.6.2
