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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/build_client_plugin.py, line 21 return subprocess.check_output(['git', '-C', str(root), *args], text=True).strip()

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/stage_client_runtime.py, line 18 with urllib.request.urlopen(URL, timeout=60) as response:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/test_client_plugin.py, line 34 self.assertNotIn('.env', z.namelist())

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.
