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

Rescanned at commit e294f94b2eb5, unchanged since the check below.

NETWORK_NO_FIXED_HOST PERMISSION_SHELL_DECLARED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    cli_use/daemon.py, line 70 with socket.create_connection(("127.0.0.1", port), timeout=0.5):

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    cli_use/daemon.py, line 104 subprocess.Popen(

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.
