I do not believe there is any possibility of sql injection vulnerability in mojoportal or any features we ship. We use parameterized queries and procedures and we never concatenate user input into sql statements.
Such tools often give false positives, if you think there is a problem you would have to provide much more specific details about where this tool thinks there is a vulnerability and on what basis it thinks that.
If you are using any custom code or third party code we cannot vouch for that, but we are very confident that no such vulnerability exists in our code.
