CVE-2026-44968: CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') in dbt-labs dbt-mcp
dbt-mcp versions prior to 1.17.1 contain a vulnerability where unsanitized input is appended to subprocess arguments, allowing argument injection of dbt global flags. This flaw is fixed in version 1.17.1.
AI Analysis
Technical Summary
The dbt-mcp Model Context Protocol server for dbt versions before 1.17.1 has an argument injection vulnerability (CWE-88) in the _run_dbt_command() function. Unsanitized node_selection and resource_type values are appended directly to the dbt subprocess argument list, enabling an MCP client to inject global dbt flags such as --profiles-dir, --project-dir, and --target. Although shell=False is used, preventing shell metacharacter injection, the injection of command arguments remains possible. The issue is resolved in version 1.17.1.
Potential Impact
An attacker with low privileges and local access can inject arbitrary dbt global flags into subprocess calls, potentially altering dbt command behavior and compromising confidentiality and integrity of operations. The CVSS score of 6.3 reflects a medium severity with high impact on confidentiality and integrity but no impact on availability. There are no known exploits in the wild.
Mitigation Recommendations
Upgrade dbt-mcp to version 1.17.1 or later where this vulnerability is fixed. No other mitigations are indicated or required.
