Mitigations: If you are unable to update in a timely manner you could remove the permission Customize dashboards and use them and Customize reports and use them from the used roles. So the users and admins cannot edit dashboards and reports anymore. Adding a Custom url with a malicious URL is blocked by the Content-Security-Policy.
