From 11.1.10 until 11.4.14 and from 12.0.0-alpha.4 until 12.0.0-alpha.5, sanitizeTranslatedHtml() escapes markup and event-handler text inside an iframe srcdoc value but leaves the srcdoc attribute active. Browsers decode the character references and parse the value as a same-origin nested HTML document, allowing attacker-controlled parameters or translation content placed in srcdoc to execute script when applications enable escapeParameter and render translations as HTML through v-html. Versions 9.14.5 and 10.0.8 are also affected and are no longer supported, while i18n-t rendering is not affected. This issue is fixed in versions 11.4.14 and 12.0.0-alpha.5.","state":0,"publishedAt":"2026-10-28T19:17:30.207+00:00","modifiedAt":"2026-10-29T21:17:15.557+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2,"severity":"HIGH"}],"references":["https://github.com/intlify/vue-i18n/commit/43391d20e7c85403cb59bdb21b5d542819f54042","https://github.com/intlify/vue-i18n/pull/2679","https://github.com/intlify/vue-i18n/releases/tag/v11.4.14","https://github.com/intlify/vue-i18n/releases/tag/v12.0.0-alpha.5","https://github.com/intlify/vue-i18n/security/advisories/GHSA-83rm-6c8r-g728"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-118257","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-79","CWE-116"],"productCriteria":[],"sourceDates":{"published":"2026-10-28T19:17:30.207","lastModified":"2026-10-29T21:17:15.557"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
