Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/smoke_test_rate_limit.py, line 47 resp = httpx.post(url, json={"email": email, "password": password, "returnSecureToken": True})

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/smoke_test_rate_limit.py, line 5 FIREBASE_EMAIL and FIREBASE_PASSWORD in .env - the script fetches the

  • PERMISSION_SHELL_DECLARED Note

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

    AGENTS.md, line 109 - **Subprocesses:** Never use `os.system` or `subprocess.run(..., shell=True)` with unvalidated input to prevent shell injection vulnerabilities.

  • SECRETS_ENV_READ Note

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

    scripts/smoke_test_rate_limit.py, line 22 _API_KEY = os.environ.get("FIREBASE_API_KEY", "")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    uv.lock, line 1 version = 1

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.
