Short explanation
CVE-2026-114131 in Nuxt allows bypassing appMiddleware because route rule keys are compared against the raw request path.
It enables unauthenticated users to access protected pages and SSR data.
What should be done?
- Follow vendor advisory guidelines
- Apply Nuxt updates
- Check for security patches
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.
Chain of evidence and sources

Yüzde kodlamalı bir segment, appMiddleware denetimini atlayarak korumalı sayfalara erişim sağlayabilir.
Show the technical text from the sources
Nuxt is an open-source web development framework for Vue.js. From 3.11.0 until 3.21.4 and 4.4.4, Nuxt compares route-rule keys with the raw request path while route resolution decodes dynamic and catch-all parameters, allowing a percent-encoded segment to resolve to a protected page without matching the routeRules entry intended for that path. As a result, appMiddleware can be skipped during server rendering and an unauthenticated requester can receive the gated page and its SSR data. The same mismatch affects app-manifest rules including redirect, appLayout, ssr, prerender, and payload flags derived from cache, isr, and swr. This vulnerability is fixed in 4.4.4 and 3.21.4.
