Rescanned at commit 3399799ee137, unchanged since the check below.

INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    requirements.txt, line 1 ddgs

  • NETWORK_NO_FIXED_HOST Low

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

    evals/fetch_datasets.py, line 52 resp = requests.get(url, timeout=timeout_secs, stream=True)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    evals/run_compression_eval.py, line 102 load_dotenv(Path(__file__).resolve().parents[1] / ".env")

  • SECRETS_ENV_READ Note

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

    webfetch/extract/claude.py, line 40 resolved_key = api_key or os.environ.get("ANTHROPIC_API_KEY")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    evals/results/matcher_eval_20260709_004727.json, line 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.
