Description

dbt-mcp is a Model Context Protocol server for interacting with dbt. Prior to 1.17.1, _run_dbt_command() in src/dbt_mcp/dbt_cli/tools.py appended unsanitized node_selection and resource_type values to the dbt subprocess argument list, allowing an MCP client to inject dbt global flags such as --profiles-dir, --project-dir, and --target into subprocess.Popen even though shell=False prevents shell metacharacter injection. This issue is fixed in version 1.17.1.

Affected products

• dbt-labs dbt-mcp: before 1.17.1 — fixed in 1.17.1

How to fix

Upgrade to a fixed version: dbt-labs dbt-mcp 1.17.1. Check the vendor advisory for mitigations.
