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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":57,"depthScoreParts":{"impact":45.1,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":225339,"id":"CVE-2026-100406","ts":1792464734045,"field":"exploit_available","old":"false","new":"true"},{"seq":221815,"id":"CVE-2026-100406","ts":1792035832429,"field":"cvss","old":null,"new":"8.2"},{"seq":221814,"id":"CVE-2026-100406","ts":1792035832429,"field":"severity","old":"none","new":"high"}]}
