Hey question about security with gitea and synology

I have a Synology server with Gitea installed and now I want to open users for my customers to be able to open repos and use it

If some customers accidentally upload a virus to their repos will it somehow put my Synology server at risk?

is there a way for me to protect via virus in gitea? (I have Synology antivirus but I am not sure if it can scan git files)
