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.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST PERMISSION_SHELL_DECLARED INSTALL_DOCUMENTED_INSTALLER
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
scripts/check-clients-matrix.py, line 299
with urllib.request.urlopen(url, timeout=30) as resp: - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
scripts/check-clients-matrix.py, line 299
with urllib.request.urlopen(url, timeout=30) as resp: - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
scripts/check-clients-matrix.py, line 249
out = subprocess.run([bin_, "wire", "--help"], capture_output=True, - INSTALL_DOCUMENTED_INSTALLER Note
Documentation shows an installer that pipes a download into a shell.
README.md, line 73
<sub>No Homebrew? <code>curl -LsSf https://nika.sh/install.sh | sh</code> · then <code>nika --version</code> confirms it.</sub>
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.
