NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/validate_server_json.py, line 17 with urllib.request.urlopen(SCHEMA_URL, timeout=20) as response:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/validate_public_snapshot.py, line 19 FORBIDDEN_PATH_PARTS = {"__pycache__", ".venv", ".env"}

  • PERMISSION_SHELL_DECLARED Note

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

    scripts/check_secret_scan.py, line 24 completed = subprocess.run(

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.
