Command Injection in dbt-mcp

Publication date: 2026-07-16

Last updated on: 2026-07-16

Assigner: GitHub, Inc.

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.

Executive Summary

CVE-2026-44968 is an argument injection flaw in dbt-mcp versions up to 1.17.0. The _run_dbt_command() function in src/dbt_mcp/dbt_cli/tools.py appends unsanitized node_selection and resource_type values to dbt subprocess arguments. This allows an MCP client to inject global flags like --profiles-dir, --project-dir, or --target into the command even with shell=False, enabling unintended behavior such as loading malicious configs or redirecting execution paths.

Detection Guidance

To detect this vulnerability, check the version of dbt-mcp installed on your system. If it is below 1.17.1, the system is vulnerable. Run: dbt-mcp --version. Additionally, review logs for suspicious dbt command executions with injected flags like --profiles-dir or --project-dir.

Impact Analysis

An attacker with local access could exploit this to override dbt settings like profiles directory or project directory. This could lead to execution with attacker-controlled database settings, potential data exposure, or unauthorized modifications to dbt projects. The impact includes high confidentiality and integrity risks under specific conditions.

Mitigation Strategies

Upgrade dbt-mcp to version 1.17.1 or later immediately. This version includes input validation to prevent flag injection. After upgrading, monitor logs for any unusual activity related to dbt command execution.
