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

Rescanned at commit eecd6250421d, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST INSTALL_DOCUMENTED_INSTALLER

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    pkg/npm/scripts/install.js, line 68 fs.unlinkSync(tarPath);

  • NETWORK_NO_FIXED_HOST Low

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

    install.sh, line 76 version=$(curl -sSf "https://api.github.com/repos/${REPO}/releases/latest" | grep '"tag_name":' | sed -E 's/.*"v([^"]+)".*/\1/')

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    install.sh, line 76 version=$(curl -sSf "https://api.github.com/repos/${REPO}/releases/latest" | grep '"tag_name":' | sed -E 's/.*"v([^"]+)".*/\1/')

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    README.md, line 198 curl -sSf https://raw.githubusercontent.com/armgabrielyan/primer/main/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.
