{"cve":"CVE-2026-47200","nvd":{"published":"2026-06-12T14:16:32.137","modified":"2026-06-17T10:54:24.377","status":"Analyzed","description":"Nuxt is an open-source web development framework for Vue.js. In Nuxt versions 3.11.0 to before 3.21.6 and 4.0.0-alpha.1 to before 4.4.6 and @nuxt/nitro-server versions 3.20.0 to before 3.21.6 and 4.0.0-alpha.1 to before 4.4.6, when experimental.componentIslands is enabled (default in Nuxt 4), any .server.vue file under pages/ is automatically registered as a server island under the key page_<routeName> and exposed via the /__nuxt_island/:name endpoint. Until this fix, requests through that endpoint rendered the page component directly via the SSR renderer without instantiating Vue Router, which meant route middleware declared on the page (including definePageMeta({ middleware })) did not run. This issue has been patched in versions 3.21.6 and 4.4.6.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-284","CWE-288"],"references":["https://github.com/nuxt/nuxt/pull/35092","https://github.com/nuxt/nuxt/security/advisories/GHSA-hg3f-28rg-4jxj","https://github.com/nuxt/nuxt/security/advisories/GHSA-hg3f-28rg-4jxj"],"products":["nuxt:nuxt","nuxt:nuxt\\/nitro-server"],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-47200","score":0.0023,"percentile":0.13825,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hg3f-28rg-4jxj","url":"https://osv.dev/vulnerability/GHSA-hg3f-28rg-4jxj","summary":"Nuxt's route middleware is not enforced when rendering `.server.vue` pages via `/__nuxt_island/page_*`","modified":"2026-07-08T17:45:16.501372548Z","packages":[{"ecosystem":"npm","name":"nuxt","purl":"pkg:npm/nuxt","ranges":[">=3.11.0 <3.21.6"],"fixed":["3.21.6"]},{"ecosystem":"npm","name":"@nuxt/nitro-server","purl":"pkg:npm/%40nuxt/nitro-server","ranges":[">=3.20.0 <3.21.6"],"fixed":["3.21.6"]},{"ecosystem":"npm","name":"@nuxt/nitro-server","purl":"pkg:npm/%40nuxt/nitro-server","ranges":[">=4.2.0 <4.4.6"],"fixed":["4.4.6"]},{"ecosystem":"npm","name":"nuxt","purl":"pkg:npm/nuxt","ranges":[">=4.0.0-alpha.1 <4.4.6"],"fixed":["4.4.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
