Microsoft Sonar test of my yunohost instance

Microsoft has launched a new online linting tool called Microsoft Sonar to test the source code, the securitu and the accessibility of web pages.
I have tested my own yunohost instance and the results are available here
My instance has not been customed at all. It is a standard yunohost config.
I can see that there are errors but I haven’t got enough skills about web technologies to analyse these results.
Could you help me?
Have you tested your own yunohost instance?
Have you got the same results?
Could it be fixed in yunohost’s next upgrades?
