Rescanned at commit af7f30280beb.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST INSTALL_DOCUMENTED_INSTALLER OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/accept_latex_counter_context.py, line 67 run = subprocess.run(argv, cwd=root, capture_output=True, timeout=240)

  • NETWORK_NO_FIXED_HOST Low

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

    src/papergraph/published.py, line 189 raw = socket.create_connection((self._address, 443), self.timeout)

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    .agents/skills/setting-up-papergraph/references/client-configuration.md, line 68 curl -LsSf https://astral.sh/uv/install.sh | sh

  • 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.
