  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    plugins/motherduck-skills/skills/motherduck-cli/references/CLI_PLAYBOOK.md, line 40 curl -s https://install.motherduck.com | SKIP_DUCKDB_CLI=1 sh

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    plugins/motherduck-skills/skills/motherduck-cli/references/CLI_PLAYBOOK.md, line 40 curl -s https://install.motherduck.com | SKIP_DUCKDB_CLI=1 sh

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    plugins/motherduck-skills-claude/skills/motherduck-create-dive/references/DIVE_DESIGN_GUIDE.md, line 197 2. Add a MotherDuck token for local preview in `.dive-preview/.env`; never commit it.

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    plugins/motherduck-skills/skills/motherduck-build-cfa-app/references/CFA_ARCHITECTURE.md, line 87 "read_token": os.environ.get("ACME_READ_TOKEN", ""),

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    plugins/motherduck-skills/skills/motherduck-build-data-pipeline/references/dlt-dbt-motherduck-project/uv.lock, line 1 version = 1

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
