NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB PERMISSION_SHELL_DECLARED 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 42 curl -fsSL "$URL" -o "$INSTALL_DIR/hera-agent-unity"

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    plugins/hera-unity/.codexignore, line 1 .env

  • OBFUSCATION_ENCODED_BLOB Low

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

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    cmd/deferred_delete_windows.go, line 37 cmd := exec.Command("powershell.exe", "-NoProfile", "-WindowStyle", "Hidden",

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    README.ko.md, line 310 curl -fsSL https://raw.githubusercontent.com/NotNull92/hera-agent-unity/main/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.
