CVE-2024-36105: dbt allows Binding to an Unrestricted IP Address via socketsocket
Binding to INADDR_ANY (0.0.0.0) or IN6ADDR_ANY (::) exposes an application on all network interfaces, increasing the risk of unauthorized access.
While doing some static analysis and code inspection, I found the following code binding a socket to INADDR_ANY by passing "" as the address. This effectively binds to any network interface on the local system, not just localhost (127.0.0.1).
