Exploited in the last 30 days

dbt enables data analysts and engineers to transform their data using the same practices that software engineers use to build applications. From 2.0.0-alpha.0 until 2.0.0-alpha.5, dbt docs serve exposes the unauthenticated POST /api/v1/query endpoint in crates/dbt-docs-server/src/handlers/query.rs, which passes caller-supplied SQL to DuckDbViewsBackend::query_arrow() in crates/dbt-index-core/src/backend.rs without authorization or an allowlist. A client that can reach the server can invoke DuckDB filesystem-reading functions to read files available to the dbt process, including files outside the docs index directory. The server binds to localhost by default, but operators can expose it to a network through the host option or DBT_DOCS_HOST setting. This issue is fixed in version 2.0.0-alpha.5.
