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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/macos_computer_use/apps.py, line 61 proc = subprocess.run(argv, capture_output=True, text=True)

  • NETWORK_NO_FIXED_HOST Low

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

    install.sh, line 49 pypi=$(curl -s -o /dev/null -w '%{time_total}' --max-time 6 https://pypi.org/simple/pip/ 2>/dev/null || echo 99)

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    install.sh, line 49 pypi=$(curl -s -o /dev/null -w '%{time_total}' --max-time 6 https://pypi.org/simple/pip/ 2>/dev/null || echo 99)

  • SECRETS_ENV_READ Note

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

    src/macos_computer_use/darwin.py, line 314 key = os.environ.get("TYPESAFE_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.
