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

Rescanned at commit c733781ac14f, unchanged since the check below.

NETWORK_NO_FIXED_HOST INSTALL_DOCUMENTED_INSTALLER

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    install.sh, line 68 RELEASE_JSON="$(curl "${CURL_OPTS[@]}" "$LATEST_URL")" \

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    README.md, line 24 curl -fsSL https://drengr.dev/install.sh | bash

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.
