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.","published":"2026-07-16T17:48:29.604Z","modified":"2026-07-23T04:02:51.474941821Z","cvss":{"score":6.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N"},"epss":{"score":0.00172,"percentile":0.06811,"asOf":"2026-08-09"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"dbt-mcp","fixedVersion":"1.17.1"}],"fix":{"url":"https://github.com/dbt-labs/dbt-mcp/commit/6534507b5e7a729758d5baece155602cad0bb22f","label":"dbt-labs/dbt-mcp@6534507"},"references":[{"type":"WEB","url":"https://github.com/dbt-labs/dbt-mcp/releases/tag/v1.17.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44968.json"},{"type":"ADVISORY","url":"https://github.com/dbt-labs/dbt-mcp/security/advisories/GHSA-xpww-f6pm-cfhq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44968"},{"type":"FIX","url":"https://github.com/dbt-labs/dbt-mcp/commit/6534507b5e7a729758d5baece155602cad0bb22f"},{"type":"FIX","url":"https://github.com/dbt-labs/dbt-mcp/pull/752"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-23T04:02:51.474941821Z"}}
