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

Rescanned at commit f44bcb257a2a, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    kogcat/hooks/cleanup_legacy_sidecars.py, line 256 proc = subprocess.run(

  • NETWORK_NO_FIXED_HOST Low

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

    kogcat/scripts/_bin_fetch_runner.py, line 141 resp = urllib.request.urlopen(req, timeout=SOCKET_TIMEOUT_S) # noqa: S310 - manifest URL

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    kogcat/scripts/_bin_fetch_runner.py, line 141 resp = urllib.request.urlopen(req, timeout=SOCKET_TIMEOUT_S) # noqa: S310 - manifest URL

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.
