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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"nuxt","product":"nuxt","versions":[{"version":">= 4.0.0, < 4.4.4","status":"affected"},{"version":">= 3.11.0, < 3.21.4","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":2.5}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-30T17:48:43.512590Z","id":"CVE-2026-114131","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-436"},{"lang":"en","value":"CWE-863"}]}],"references":[{"url":"https://github.com/nuxt/nuxt/commit/81f86ac5ee82bb1a9b887e59f3bc84624d711497","source":"security-advisories@github.com"},{"url":"https://github.com/nuxt/nuxt/commit/9123ed850c468a7424a868c20d0d49a5507d32e5","source":"security-advisories@github.com"},{"url":"https://github.com/nuxt/nuxt/releases/tag/v3.21.11","source":"security-advisories@github.com"},{"url":"https://github.com/nuxt/nuxt/releases/tag/v4.5.2","source":"security-advisories@github.com"},{"url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-6gq8-jgmh-3ffp","source":"security-advisories@github.com"}]}
