Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

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

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/ironbench/cli.py, line 580 shutil.rmtree(stale, ignore_errors=True)

  • NETWORK_NO_FIXED_HOST Low

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

    src/ironbench/runner_renode.py, line 446 sock = socket.create_connection(("localhost", port), timeout=1.0)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/ironbench/agent.py, line 9 Config - environment variables (or .env): LLM_BASE_URL (defaults to local

  • SECRETS_ENV_READ Note

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

    src/ironbench/runner_common.py, line 240 if os.environ.get("WOKWI_CLI_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.
