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

Rescanned at commit 657ad6576613, unchanged since the check below.

NETWORK_NO_FIXED_HOST PERMISSION_SHELL_DECLARED INSTALL_DOCUMENTED_INSTALLER OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/stats.py, line 27 with urllib.request.urlopen(req, timeout=15) as resp:

  • PERMISSION_SHELL_DECLARED Note

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

    scripts/probe_stdio.py, line 12 proc = subprocess.Popen(

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    README.md, line 76 curl -LsSf https://astral.sh/uv/install.sh | sh

  • 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.

What was checked

Plain notes from the hygiene checks.

    Note

    requests shell access. The manifest names this permission.
