Grades are a hygiene check, not a security guarantee.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    final_test.py, line 221 os.remove(tmp)

  • NETWORK_NO_FIXED_HOST Low

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

    test_frontend.py, line 15 r = requests.get('http://127.0.0.1:3000', timeout=10)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    deploy.sh, line 5 # Usage: cp .env.example .env -> fill DOMAIN, EMAIL, GOOGLE_* -> ./deploy.sh

  • SECRETS_ENV_READ Note

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

    frontend/lib/auth.ts, line 5 const clientSecret = process.env.GOOGLE_CLIENT_SECRET || "dummy";

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.
