It converts strings according to the following rules:\n\nhttps://github.com/QwikDev/qwik/blob/v1.5.5/packages/qwik/src/core/render/ssr/render-ssr.ts#L1182-L1208\n\n- If the string is an attribute value:\n - `\"` -> `"`\n - `&` -> `&`\n - Other characters -> No conversion\n- Otherwise:\n - `<` -> `<`\n - `>` -> `>`\n - `&` -> `&`\n - Other characters -> No conversion\n\nIt sometimes causes the situation that the final DOM tree rendered on browsers is different from what Qwik expects on server-side rendering. This may be leveraged to perform XSS attacks, and a type of the XSS is known as mXSS (mutation XSS).\n\n## PoC\n\nA vulnerable component:\n```javascript\nimport { component$ } from \"@builder.io/qwik\";\nimport { useLocation } from \"@builder.io/qwik-city\";\n\nexport default component$(() => {\n \n // user input\n const { url } = useLocation();\n const href = url.searchParams.get(\"href\") ?? \"https://example.com\";\n\n return (\n
\n \n
