A reflected cross-site scripting (XSS) vulnerability exists in FuguHub 8.1 when serving SVG files through the /fs/ file manager interface. FuguHub does not sanitize or restrict script execution inside SVG content. When a victim opens a crafted SVG containing an inline <script> element, the browser executes the attacker-controlled JavaScript.

Real Time Logic FuguHub v8.1 and earlier was discovered to contain a remote code execution (RCE) vulnerability via the component /FuguHub/cmsdocs/.
