Graded by PlugVetRubric v2

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

Rescanned at commit 45b65f260196, unchanged since the check below.

NETWORK_NO_FIXED_HOST INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ 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.

    docs/installs/Django/netbox/4.x/development/test_oauth_flow.py, line 51 with urllib.request.urlopen(req) as resp:

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    docs/v1.0/Getting Started/getting-started.md, line 29 RUN curl -LsSf https://astral.sh/uv/install.sh | sh

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    docs/installs/Django/nautobot/3.x/development/nautobot_config.py, line 51 "PASSWORD": os.getenv("NAUTOBOT_DB_PASSWORD", "changeme"),

  • 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.
