"summary": "vue-i18n's escapeParameterHtml does not prevent DOM-based XSS through its tag attributes",
10+
"details": "### Summary\nThe escapeParameterHtml: true option in Vue I18n is designed to protect against HTML/script injection by escaping interpolated parameters. However, this setting fails to prevent execution of certain tag-based payloads, such as <img src=x onerror=...>, if the interpolated value is inserted inside an HTML context using v-html.\n\nThis may lead to a DOM-based XSS vulnerability, even when using escapeParameterHtml: true, if a translation string includes minor HTML and is rendered via v-html.\n\n### Details\n\nWhen escapeParameterHtml: true is enabled, it correctly escapes common injection points.\n\nHowever, it does not sanitize entire attribute contexts, which can be used as XSS vectors via:\n\n`<img src=x onerror=alert(1)>\n`\n### PoC\nIn your Vue I18n configuration:\n\n```\nconst i18n = createI18n({\n escapeParameterHtml: true,\n messages: {\n en: {\n vulnerable: 'Caution: <img src=x onerror=\"{payload}\">'\n }\n }\n});\n```\nUse this interpolated payload:\n\n`const payload = '<script>alert(\"xss\")</script>';`\nRender the translation using v-html (even not using v-html):\n\n`<p v-html=\"$t('vulnerable', { payload })\"></p>\n`\nExpected: escaped content should render as text, not execute.\n\nActual: script executes in some environments (or the payload is partially parsed as HTML).\n\n### Impact\n\nThis creates a DOM-based Cross-Site Scripting (XSS) vulnerability despite enabling a security option (escapeParameterHtml) .",
