Description
dbt enables data analysts and engineers to transform their data using the same practices that software engineers use to build applications. Prior to versions 1.6.15, 1.7.15, and 1.8.1, Binding to `INADDR_ANY (0.0.0.0)` or `IN6ADDR_ANY (::)` exposes an application on all network interfaces, increasing the risk of unauthorized access. As stated in the Python docs, a special form for address is accepted instead of a host address: `''` represents `INADDR_ANY`, equivalent to `"0.0.0.0"`. On systems with IPv6, '' represents `IN6ADDR_ANY`, which is equivalent to `"::"`. A user who serves docs on an unsecured public network, may unknowingly be hosting an unsecured (http) web site for any remote user/system to access on the same network. The issue has has been mitigated in dbt-core v1.6.15, dbt-core v1.7.15, and dbt-core v1.8.1 by binding to localhost explicitly by default in `dbt docs serve`.
