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

Rescanned at commit 922b61c61e86, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    examples/agents/memory_loop_agent.py, line 29 r = httpx.post(f"{BASE.rstrip('/')}/chat/completions", timeout=120,

  • SECRETS_ENV_READ Note

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

    examples/agents/langgraph_agent.py, line 20 LLM_API_KEY = os.environ.get("LLM_API_KEY") or os.environ.get("GROQ_API_KEY") or os.environ.get("OPENAI_API_KEY")

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.
