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":"2026-10-21T17:41:24.016+00:00","modifiedAt":"2026-10-21T17:41:24.016+00:00","affected":[{"ecosystem":"Vendor product","name":"nuxt","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nuxt\",\n                    \"product\": \"nuxt\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 4.0.0, < 4.4.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.11.0, < 3.21.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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/security/advisories/GHSA-6gq8-jgmh-3ffp","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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-114131","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-114131","identifiers":["CVE-2026-114131"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
