The product assigns the address 0.0.0.0 for a database server, a cloud service/instance, or any computing resource that communicates remotely.
When a server binds to the address 0.0.0.0, it allows connections from every IP address on the local machine, effectively exposing the server to every possible network. This might be much broader access than intended by the developer or administrator, who might only be expecting the server to be reachable from a single interface/network.
Assign IP addresses that are not 0.0.0.0.
Unwanted connections to the configured server may be denied through a firewall or other packet filtering measures.
