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

Rescanned at commit 07868b1a0516, unchanged since the check below.

PERMISSION_SHELL_UNDECLARED INSTALL_REMOTE_SCRIPT

Why this grade

  • PERMISSION_SHELL_UNDECLARED Medium

    Runs shell commands that the manifest or description does not mention.

    cli/src/pydantic_rpc_cli/cli.py, line 203 proc = subprocess.Popen(cmd, env=env)

  • INSTALL_REMOTE_SCRIPT Medium

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    README.md, line 1239 curl --proto '=https' --tlsv1.2 -sSf https://just.systems/install.sh | bash -s -- --to ~/bin

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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Concern

    requests shell access. No manifest field names shell or command execution.

    PERMISSION_SHELL_UNDECLARED

    cli/src/pydantic_rpc_cli/cli.py, line 203

    proc = subprocess.Popen(cmd, env=env)

    cli/src/pydantic_rpc_cli/cli.py, line 254

    proc = subprocess.Popen(cmd, env=env)

  • Install and update

    Serious

    install fetches a script from the network. README documents an installer that pipes a download into a shell.

    INSTALL_REMOTE_SCRIPT INSTALL_DOCUMENTED_INSTALLER

    README.md, line 1239

    curl --proto '=https' --tlsv1.2 -sSf https://just.systems/install.sh | bash -s -- --to ~/bin

    examples/README.md, line 10

    curl -LsSf https://astral.sh/uv/install.sh | sh

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

    examples/olympics_asgi_anthropic.py, line 80

    print("\nExample curl commands:")

    examples/olympics_asgi_anthropic.py, line 82

    f" curl -X POST http://localhost:{port}/olympicsagent.v1.OlympicsAgent/ask \\"

    examples/error_handler/server_asgi.py, line 126

    print(' curl -X POST http://localhost:8000/examples.error_handler.v1.UserService/CreateUser \\')

    Show more

    examples/error_handler/server_wsgi.py, line 129

    print(' curl -X POST http://localhost:3000/examples.error_handler.v1.UserService/CreateUser \\')

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_ENV_READ SECRETS_PATH_UNCONFIRMED

    examples/olympics_asgi_anthropic.py, line 40

    api_key = os.environ.get("ANTHROPIC_API_KEY")

    .gitignore, line 16

    .devcontainer/

  • Agent instructions

    Pass

    No instruction to ignore earlier instructions or to hide a step.

  • Obfuscation

    Concern

    contains a minified payload.

    OBFUSCATION_MINIFIED_PAYLOAD

    examples/error_handler/userservice_pb2.py, line 27

    DESCRIPTOR = _descriptor_pool.Default().AddSerializedFile(b'\n\x11userservice.proto\x12\x19\x65xamples.error_handler.v1\"0\n\x0cUserResponse\x12\x0f\n\x07message\x18\x01 \x01(\t\x1
