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":"2026-10-28T18:23:49.4+00:00","modifiedAt":"2026-10-29T20:55:05.78+00:00","affected":[{"ecosystem":"Vendor product","name":"vue-i18n","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"intlify\",\n                    \"product\": \"vue-i18n\",\n                    \"versions\": [\n                        {\n                            \"version\": \"= 9.14.5\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"= 10.0.8\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 11.1.10, < 11.4.14\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 12.0.0-alpha.4, < 12.0.0-alpha.5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","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/security/advisories/GHSA-83rm-6c8r-g728","https://github.com/intlify/vue-i18n/pull/2679","https://github.com/intlify/vue-i18n/commit/43391d20e7c85403cb59bdb21b5d542819f54042","https://github.com/intlify/vue-i18n/releases/tag/v11.4.14","https://github.com/intlify/vue-i18n/releases/tag/v12.0.0-alpha.5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-118257","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-118257","identifiers":["CVE-2026-118257"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
