{"cve":"CVE-2026-114132","nvd":{"published":"2026-10-21T18:17:26.113","modified":"2026-10-23T15:17:25.530","status":"Awaiting Analysis","description":"Nuxt is an open-source web development framework for Vue.js. Prior to 4.6.2, Nuxt resolves pages case-insensitively by default while Nitro matches server-side route-rule keys case-sensitively, allowing a request whose path differs only by letter case to render without the server rule intended for that page. The mismatch can skip redirect, headers, proxy, ssr: false, and noScripts, and can cause getRouteRules(event) and matchRouteRules to return no rule for the case variant. Applications that set router.options.sensitive: true in nuxt.config are not affected; setting sensitive only in app/router.options.ts does not establish this exclusion because the server follows the nuxt.config value. Access checks implemented in server middleware, page route middleware, or page data fetching remain independent of this matcher. This issue is fixed in version 4.6.2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":6.3},"cvss_v3":null,"cwes":["CWE-178","CWE-863"],"references":["https://github.com/nuxt/nuxt/commit/f6cfee52cf9576ddc4f4ee83b486969328b358f8","https://github.com/nuxt/nuxt/releases/tag/v4.6.2","https://github.com/nuxt/nuxt/security/advisories/GHSA-vjh5-4x84-xrqp"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-114132","score":0.00424,"percentile":0.36416,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-vjh5-4x84-xrqp","url":"https://osv.dev/vulnerability/GHSA-vjh5-4x84-xrqp","summary":"Nuxt: Server-side route rules (`redirect`, `headers`, `proxy`, `ssr`) are skipped for case-variant paths when routing is case-insensitive","modified":"2026-10-22T17:15:04.297280606Z","packages":[{"ecosystem":"npm","name":"nuxt","purl":"pkg:npm/nuxt","ranges":[">=4.0.0 <4.6.2"],"fixed":["4.6.2"]},{"ecosystem":"npm","name":"nuxt","purl":"pkg:npm/nuxt","ranges":[">=3.0.0"],"fixed":[]},{"ecosystem":"npm","name":"@nuxt/nitro-server","purl":"pkg:npm/%40nuxt/nitro-server","ranges":[">=4.2.0 <4.6.2"],"fixed":["4.6.2"]},{"ecosystem":"npm","name":"@nuxt/nitro-server","purl":"pkg:npm/%40nuxt/nitro-server","ranges":[">=3.20.0"],"fixed":[]}]}],"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).
