CVE-2026-44968: CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') in dbt-labs dbt-mcp
CVE-2026-44968 is a vulnerability in dbt-labs dbt-mcp prior to version 1.17.1 where unsanitized input is appended to subprocess arguments, allowing argument injection. This flaw permits an MCP client to inject dbt global flags into subprocess.Popen calls, potentially altering command execution parameters. The issue is fixed in version 1.17.1.
AI Analysis
Technical Summary
The vulnerability exists in the _run_dbt_command() function within src/dbt_mcp/dbt_cli/tools.py of dbt-mcp versions before 1.17.1. Unsanitized values for node_selection and resource_type are appended directly to the argument list for subprocess.Popen. Although shell=False prevents shell metacharacter injection, this improper neutralization of argument delimiters (CWE-88) allows injection of dbt global flags such as --profiles-dir, --project-dir, and --target. This can lead to unintended command execution behavior. The vulnerability is resolved in dbt-mcp version 1.17.1.
Potential Impact
An attacker with low privileges and local access can inject arbitrary dbt global flags into subprocess commands, potentially altering the behavior of dbt executions. This can lead to unauthorized information disclosure or modification of dbt command context. The CVSS 3.1 score is 6.3 (medium severity) reflecting high impact on confidentiality and integrity but no impact on availability.
Mitigation Recommendations
Upgrade dbt-mcp to version 1.17.1 or later where this vulnerability is fixed. No other mitigation is indicated or required as the issue is resolved in this official fix.
