Grade D

Two or more Medium findings, or a High. Only try it in a sandbox.

Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

INSTALL_REMOTE_SCRIPT OBFUSCATION_ENCODED_BLOB

Why this grade

  • INSTALL_REMOTE_SCRIPT Medium

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    .github/actions/setup-python/action.yml, line 29 curl -LsSf https://astral.sh/uv/install.sh | sh

  • OBFUSCATION_ENCODED_BLOB Medium

    Contains a long base64 shaped string in a file that should be readable.

    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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Concern

    can delete files.

    PERMISSION_DELETE_FILES

    src/client/generated/api_client.py, line 732

    os.remove(path)

    specs/implementation-artifacts/9-2-development-plan.md, line 526

    result = subprocess.run([binary, "--version"])

  • Install and update

    Serious

    install fetches a script from the network. README documents an installer that pipes a download into a shell.

    INSTALL_REMOTE_SCRIPT INSTALL_DOCUMENTED_INSTALLER

    README.md, line 44

    1. **Install uv**: `curl -LsSf https://astral.sh/uv/install.sh | sh`

    .github/actions/setup-python/action.yml, line 29

    curl -LsSf https://astral.sh/uv/install.sh | sh

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

    docs/mcp-registry.html, line 947

    const response = await fetch("./mcp_manifest.json", { cache: "no-store" });

    specs/testing-artifacts/test-review-story-1.4.md, line 125

    **Why This Is Good**: The test asserts the returned object AND performs a fresh fetch (`service.get_test_case`) to verify the state was actually persisted to the server.

    src/services/attachment_download_service.py, line 444

    result = await fetch(owner_id, page=page, size=100)

    Show more

    src/services/test_result_service.py, line 291

    return await self._collect_pages(lambda page: fetch(test_result_id, page=page, size=PAGE_SIZE))

    src/services/test_result_service.py, line 298

    page = await fetch(requested_page)

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_PATH_DOTENV

    scripts/full-test-suite.sh, line 25

    if [[ -f .env.test ]]; then

    scripts/full-test-suite.sh, line 26

    uv run --extra dev --env-file .env.test pytest tests/e2e -n auto -rs

    scripts/full-test-suite.sh, line 28

    echo "Skipping E2E tests: .env.test not found"

    Show more

    .env.test.example, line 2

    # Copy this file to .env.test and fill in your actual sandbox credentials

    .github/workflows/_python_check.yml, line 52

    echo "CI=true" > .env.test

    .github/workflows/_python_check.yml, line 53

    uv run --python ${{ inputs.python-version }} --env-file .env.test pytest tests/unit/ tests/integration/ tests/docs/ --cov=src --cov-report=term-missing -v

    .gitignore, line 1

    .DS_Store

    .gitignore, line 2

    .env

  • Agent instructions

    Pass

    No instruction to ignore earlier instructions or to hide a step.

  • Obfuscation

    Concern

    contains an encoded blob in a file that should be readable.

    OBFUSCATION_ENCODED_BLOB

    uv.lock, line 1
