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

Rescanned at commit 7184b6bba578, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/ogham/importers/beads.py, line 21 proc = subprocess.run(args, cwd=cwd, capture_output=True, text=True) # noqa: S603

  • NETWORK_NO_FIXED_HOST Low

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

    benchmarks/locomo_benchmark.py, line 15 curl -L -o benchmarks/locomo10.json \

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    benchmarks/beam_benchmark.py, line 41 - Local Postgres with pgvector (benchmarks/.env.local)

  • SECRETS_ENV_READ Note

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

    src/ogham/cli.py, line 965 token = os.environ.get("LINEAR_API_TOKEN")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    uv.lock, line 1 version = 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.
