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

Rescanned at commit fed7f64ef439, unchanged since the check below.

PERMISSION_SHELL_UNDECLARED

Why this grade

  • PERMISSION_SHELL_UNDECLARED Medium

    Runs shell commands that the manifest or description does not mention.

    scripts/simulation.py, line 866 subprocess.check_call([sys.executable, "-m", "pip", "install", "--user", "--break-system-packages", "neo4j", "-q"])

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.

  • Permissions

    Concern

    requests shell access. No manifest field names shell or command execution.

    PERMISSION_SHELL_UNDECLARED

    scripts/simulation.py, line 866

    subprocess.check_call([sys.executable, "-m", "pip", "install", "--user", "--break-system-packages", "neo4j", "-q"])

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

  • Secrets

    Concern

    reads a credential or environment file.
