Graded by PlugVetRubric v2

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

NETWORK_NO_FIXED_HOST PERMISSION_SHELL_DECLARED SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    setup/gws_bridge.py, line 54 with urllib.request.urlopen(req, timeout=15) as resp:

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    setup/google_api.py, line 117 result = subprocess.run(

  • SECRETS_ENV_READ Note

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

    server.py, line 71 TOKEN_PATH = Path(os.environ.get("GOOGLE_TOKEN_PATH", _state_home() / "google_token.json"))

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.
