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

Rescanned at commit 94e22a4c5dcd, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    src/medium_ops/cli.py, line 193 if not curl and not sys.stdin.isatty():

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/medium_ops/cli.py, line 121 env_path: Path = typer.Option(Path(".env"), "--env", help="Where to write extracted cookies."),

  • PERMISSION_SHELL_DECLARED Note

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

    src/medium_ops/llm_subprocess.py, line 102 result = subprocess.run(

  • SECRETS_ENV_READ Note

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

    src/medium_ops/cli.py, line 177 console.print(f"[green]updated .env[/green] keys: {updated}")

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.
