## What is CVE-2026-44968?

CVE-2026-44968 is a medium-severity command injection vulnerability in dbt-labs dbt-mcp, published on 16 Jul 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official 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.

Weakness: CWE-88 (Improper Neutralization of Argument Delimiters in a Command)

Affected packages and fixed versions:
- dbt-mcp (PyPI): affected all versions; fixed in 1.17.1
- dbt-mcp (PyPI): affected all versions; fixed in 1.17.1
- dbt-mcp (PyPI): affected all versions; fixed in 1.17.1

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
