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.","state":0,"publishedAt":"2026-10-21T18:17:25.957+00:00","modifiedAt":"2026-10-22T16:46:48.92+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/nuxt/nuxt/commit/81f86ac5ee82bb1a9b887e59f3bc84624d711497","https://github.com/nuxt/nuxt/commit/9123ed850c468a7424a868c20d0d49a5507d32e5","https://github.com/nuxt/nuxt/releases/tag/v3.21.11","https://github.com/nuxt/nuxt/releases/tag/v4.5.2","https://github.com/nuxt/nuxt/security/advisories/GHSA-6gq8-jgmh-3ffp"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-114131","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-436","CWE-863"],"productCriteria":[],"sourceDates":{"published":"2026-10-21T18:17:25.957","lastModified":"2026-10-22T16:46:48.920"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
