      "value": "ComfyUI is a modular diffusion model GUI, api and backend with a graph/nodes interface. Prior to 0.28.0, the /view endpoint served uploaded SVG files inline because image/svg+xml and related XML content types were absent from the dangerous-content-type handling, allowing stored cross-site scripting in the ComfyUI origin. This issue is fixed in version 0.28.0."

Antes de la versión 0.28.0, el endpoint /view servía archivos SVG subidos en línea porque los tipos de contenido image/svg+xml y XML relacionados estaban ausentes del manejo de tipos de contenido peligrosos, lo que permitía cross-site scripting almacenado en el origen de ComfyUI. Este problema está solucionado en la versión 0.28.0."
