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.","state":0,"publishedAt":"2026-10-14T18:27:24.863+00:00","modifiedAt":"2026-10-20T01:51:20.549+00:00","affected":[{"ecosystem":"Vendor product","name":"dbt-core","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"dbt-labs\",\n                    \"product\": \"dbt-core\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.0.0-alpha.0, < 2.0.0-alpha.5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.2,"severity":"HIGH"}],"references":["https://github.com/dbt-labs/dbt/security/advisories/GHSA-h2j2-2r7g-rff8","https://github.com/dbt-labs/dbt/commit/3a5d26fe02b58382720d04cbd87143b7b6775413","https://github.com/dbt-labs/dbt/releases/tag/v2.0.0-alpha.5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100406","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100406","identifiers":["CVE-2026-100406"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
