Fiora chat group avatar is vulnerable to XSS via SVG files
File upload vulnerability in Fiora chat application 1.0.0 through user avatar upload functionality. The application fails to validate SVG file content, allowing malicious SVG files with embedded foreignObject elements containing iframe tags and JavaScript event handlers (onmouseover) to be uploaded and stored.
