CVE-2025-66470

NiceGUI is a Python-based UI framework. Versions 3.3.1 and below are subject to a XSS vulnerability through the ui.interactive_image component of NiceGUI. The component renders SVG content using Vue's v-html directive without any sanitization. This allows attackers to inject malicious HTML or JavaScript via the SVG <foreignObject> tag whenever the image component is rendered or updated. This is particularly dangerous for dashboards or multi-user applications displaying user-generated content or annotations. This issue is fixed in version 3.4.0.

El componente renderiza contenido SVG utilizando la directiva v-html de Vue sin ninguna sanitización. Esto permite a los atacantes inyectar HTML o JavaScript malicioso a través de la etiqueta SVG <foreignObject> cada vez que el componente de imagen es renderizado o actualizado.
