Description
The UniFi Video Server (Windows) web interface configuration restore functionality at the “backup” and “wizard” endpoints does not implement sufficient privilege checks. Low privileged users, belonging to the PUBLIC_GROUP or CUSTOM_GROUP groups, can access these endpoints and overwrite the current application configuration.

Fixed in UniFi Video Controller v3.9.6 and newer.
