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

Rescanned at commit d2f9407554f9, unchanged since the check below.

SECRETS_PATH_DOTENV NETWORK_LOCALHOST SECRETS_ENV_READ

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 1 .env

  • NETWORK_LOCALHOST Note

    Calls localhost only.

    docker-compose.yml, line 36 test: ["CMD", "python", "-c", "import urllib.request; urllib.request.urlopen('http://127.0.0.1:8000/health', timeout=5)"]

  • SECRETS_ENV_READ Note

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

    server/config.py, line 31 write_token: str = field(default_factory=lambda: os.getenv("WRITE_TOKEN", "local-development-only"))

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.
