Graded by PlugVetRubric v2

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_UNCONFIRMED OBFUSCATION_ENCODED_BLOB INSTALL_DOCUMENTED_INSTALLER

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    packaging/smoke.py, line 34 with subprocess.Popen(

  • NETWORK_NO_FIXED_HOST Low

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

    recon/http_common.py, line 85 """``fetch(url, headers, timeout)``: one GET, any status returned, never a redirect."""

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    .gitignore, line 15 # Local

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

    uv.lock, line 1 version = 1

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    README.md, line 68 curl -LsSf https://astral.sh/uv/install.sh | sh

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.

    README documents an installer that pipes a download into a shell.

    INSTALL_DOCUMENTED_INSTALLER

    README.md, line 68

    curl -LsSf https://astral.sh/uv/install.sh | sh

  • Network

    Concern

    NETWORK_NO_FIXED_HOST

    recon/http_common.py, line 85

    """``fetch(url, headers, timeout)``: one GET, any status returned, never a redirect."""

    recon/http_common.py, line 217

    reply = fetch(url, headers, TIMEOUT)
