Summary		(es) Snipe-IT es un sistema de gestión de activos/licencias de TI. Antes de la versión 8.6.2, UploadFileRequest sanitiza el contenido SVG solo cuando PHP finfo informa image/svg+xml y UploadedFilesController sirve los adjuntos en línea sin usar StorageHelper::allowSafeInline(), permitiendo a un usuario con bajos privilegios subir contenido XHTML o XML activo que luego se sirve con el mismo origen y ejecuta JavaScript en el navegador de un espectador. Este problema se solucionó en la versión 8.6.2.
