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

Rescanned at commit 0191e83a5113, unchanged since the check below.

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.

    flowllm/components/agent_wrapper/cc_agent_wrapper.py, line 180 shutil.rmtree(target)

  • NETWORK_NO_FIXED_HOST Low

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

    flowllm/lite/flow/remote_client_flow.py, line 38 resp = requests.get(f"http://{host}:{port}{path}", params=params, timeout=10)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    flowllm/components/agent_wrapper/as_agent_wrapper.py, line 177 project_env = self.project_path / ".env"

  • SECRETS_ENV_READ Note

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

    flowllm/components/agent_wrapper/cc_agent_wrapper.py, line 149 os.getenv("ANTHROPIC_AUTH_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.
