From 4.6.0 until 4.6.3, Nuxt resolves literal or percent-encoded dot segments before rendering a page while Nitro routing, server/middleware checks, and server route rules evaluate the unresolved path. A request such as /%2e/admin can therefore render app/pages/admin.vue and its server-rendered data while checks keyed to /admin, redirects, or per-route security headers do not apply. API handlers, appMiddleware, Nuxt 3, and Nuxt 4.0.0 through 4.5.x are not affected, and exploitation requires a client that sends dot segments without browser normalization. This issue is fixed in version 4.6.3."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"nuxt","product":"nuxt","versions":[{"version":">= 4.6.0, < 4.6.3","status":"affected"}]},{"vendor":"@nuxt","product":"nitro-server","versions":[{"version":">= 4.6.0, < 4.6.3","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":"2026-11-04T01:41:18.080980Z","id":"CVE-2026-119200","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-41"},{"lang":"en","value":"CWE-436"},{"lang":"en","value":"CWE-863"}]}],"references":[{"url":"https://github.com/nuxt/nuxt/commit/45463f8b58487e387149ebfb704d6a0834b3a450","source":"security-advisories@github.com"},{"url":"https://github.com/nuxt/nuxt/releases/tag/v4.6.3","source":"security-advisories@github.com"},{"url":"https://github.com/nuxt/nuxt/security/advisories/GHSA-9v7c-q64q-vv33","source":"security-advisories@github.com"}]}
