to XSS\n### Summary\nIn the default configuration of mermaid 11.9.0, user supplied input for architecture diagram icons is passed to the d3 `html()` method, creating a sink for cross site scripting.\n\n### Details\nArchitecture diagram service `iconText` values are passed to the d3 `html()` method, allowing malicious users to inject arbitrary HTML and cause XSS when mermaid-js is used in it's default configuration. \n\nThe vulnerability lies here:\n\n```ts\nexport const drawServices = async function (\n db: ArchitectureDB,\n elem: D3Element,\n services: ArchitectureService[]\n): Promise<number> {\n for (const service of services) {\n /** ... **/\n } else if (service.iconText) {\n bkgElem.html(\n `<g>${await getIconSVG('blank', { height: iconSize, width: iconSize, fallbackPrefix: architectureIcons.prefix })}</g>`\n );\n const textElemContainer = bkgElem.append('g');\n const fo = textElemContainer\n .append('foreignObject')\n .attr('width', iconSize)\n .attr('height', iconSize);\n const divElem = fo\n .append('div')\n .attr('class', 'node-icon-text')\n .attr('style', `height: ${iconSize}px;`)\n .append('div')\n .html(service.iconText); // <-
