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 .","state":0,"publishedAt":"2026-10-21T17:52:09.381+00:00","modifiedAt":"2026-10-28T17:23:40.538+00:00","affected":[{"ecosystem":"Vendor product","name":"nuxt","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nuxt\",\n                    \"product\": \"nuxt\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 3.13.0, < 4.6.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"MEDIUM"}],"references":["https://github.com/nuxt/nuxt/security/advisories/GHSA-xfq5-w38q-pc2x","https://github.com/nuxt/nuxt/commit/493565e99451a0f52330b1f6b979254a4a39e5d0","https://github.com/nuxt/nuxt/releases/tag/v4.6.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-114133","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-114133","identifiers":["CVE-2026-114133"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
