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

PERMISSION_DELETE_FILES INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB OBFUSCATION_MINIFIED_PAYLOAD SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    entry/bot.py, line 198 subprocess.run([sys.executable, os.path.join(ROOT, 'walkkcal', 'render.py')],

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    requirements.txt, line 20 Pillow>=10

  • NETWORK_NO_FIXED_HOST Low

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

    entry/bot.py, line 70 with urllib.request.urlopen(TG % (TOKEN, method), data=data,

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .dockerignore, line 4 .env

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

    corpus/local_dish_heat.json, line 1 {

  • OBFUSCATION_MINIFIED_PAYLOAD Low

    Contains a very long line with almost no spaces in a script or style file.

    corpus/local_dish_heat.json, line 1 {

  • SECRETS_ENV_READ Note

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

    entry/bot.py, line 42 TOKEN = os.environ.get('TELEGRAM_BOT_TOKEN', '')

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.
