{"id":"GHSA-x8qp-wqqm-57ph","summary":"vue-i18n's escapeParameterHtml does not prevent DOM-based XSS through its tag attributes","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 `\u003cimg src=x onerror=...\u003e`, 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`\u003cimg src=x onerror=alert(1)\u003e\n`\n### PoC\nIn your Vue I18n configuration:\n\n```\nconst i18n = createI18n({\n  escapeParameterHtml: true,\n  messages: {\n    en: {\n      vulnerable: 'Caution: \u003cimg src=x onerror=\"{payload}\"\u003e'\n    }\n  }\n});\n```\nUse this interpolated payload:\n\n`const payload = '\u003cscript\u003ealert(\"xss\")\u003c/script\u003e';`\nRender the translation using v-html (even not using v-html):\n\n`\u003cp v-html=\"$t('vulnerable', { payload })\"\u003e\u003c/p\u003e\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)
