Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/tavle.py, line 37 with urllib.request.urlopen(urllib.request.Request(url, headers=UA), timeout=timeout) as r:

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    scripts/tavle.py, line 37 with urllib.request.urlopen(urllib.request.Request(url, headers=UA), timeout=timeout) as r:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    README.md, line 65 can contain a password manager mid-unlock, a `.env` open in the editor, or

  • PERMISSION_SHELL_DECLARED Note

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

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.
