+  "details": "### Summary\n\nA potential XSS vulnerability exists in Svelte for versions prior to 4.2.19.\n\n### Details\n\nSvelte improperly escapes HTML on server-side rendering. It converts strings according to the following rules:\n\n- If the string is an attribute value:\n    - `\"` -> `&quot;`\n    - `&` -> `&amp;`\n    - Other characters -> No conversion\n- Otherwise:\n    - `<` -> `&lt;`\n    - `&` -> `&amp;`\n    - Other characters -> No conversion\n\nThe assumption is that attributes will always stay as such, but in some situation the final DOM tree rendered on browsers is different from what Svelte expects on server-side rendering. This may be leveraged to perform XSS attacks. More specifically, this can occur when injecting malicious content into an attribute within a `<noscript>` tag.\n\n### PoC\n\nA vulnerable page (`+page.svelte`):\n```html\n<script>\nimport { page } from \"$app/stores\"\n\n// user input\nlet href = $page.url.searchParams.get(\"href\") ?? \"https://example.com\";\n</script>\n\n<noscript>\n  <a href={href}>test</a>\n</noscript>\n```\n\nIf a user accesses the following URL,\n```\nhttp://localhost:4173/?href=</noscript><script>alert(123)</script>\n```\nthen, `alert(123)` will be executed.\n\n### Impact\n\nXSS, when using an attribute within a noscript tag",
