{"cve":"CVE-2026-114133","nvd":{"published":"2026-10-21T18:17:26.260","modified":"2026-10-22T16:46:48.920","status":"Awaiting Analysis","description":"Nuxt is an open-source web development framework for Vue.js. From 3.13.0 until 4.6.2, the server-island renderer serializes raw useHeadSafe entry input into the island response without preserving the safe-input marker, and NuxtIsland later inserts that input into the page head as an ordinary entry. An application that passes attacker-controlled data to useHeadSafe in a .server.vue component or page, or in a component rendered through NuxtIsland, can therefore render values normally removed by the allowlist, including event-handler attributes or executable script content, resulting in stored cross-site scripting in the application origin. This issue is fixed in version 4.6.2 .","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79"],"references":["https://github.com/nuxt/nuxt/commit/493565e99451a0f52330b1f6b979254a4a39e5d0","https://github.com/nuxt/nuxt/releases/tag/v4.6.2","https://github.com/nuxt/nuxt/security/advisories/GHSA-xfq5-w38q-pc2x"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-114133","score":0.0022,"percentile":0.12458,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-xfq5-w38q-pc2x","url":"https://osv.dev/vulnerability/GHSA-xfq5-w38q-pc2x","summary":"Nuxt server islands render `useHeadSafe` input without sanitisation","modified":"2026-10-22T17:15:04.291934160Z","packages":[{"ecosystem":"npm","name":"nuxt","purl":"pkg:npm/nuxt","ranges":[">=3.13.0 <4.6.2"],"fixed":["4.6.2"]}]}],"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).
