To tie a request made over CGNAT to the ISP's customer you need both the IP address and the port number of the connection. In my experience, most software that logs IP addresses doesn't bother to log the port number. (Probably because it wasn't relevant before CGNAT came along.)

In that case the ISP would not be able to map the address to a customer, so no one would be getting wrongfully arrested.
