PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    core/cli/cmd/upgrade.go, line 132 cmd := exec.Command(execPath, "--version")

  • NETWORK_NO_FIXED_HOST Low

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

    install.sh, line 116 latest_tag=$(curl -sL "$api_url" | grep '"tag_name":' | sed -E 's/.*"tag_name": "([^"]+)".*/\1/' | head -1)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    main.go, line 17 // Load .env files from multiple locations:

  • INSTALL_DOCUMENTED_INSTALLER Note

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

    CHANGELOGS.md, line 330 curl -fsSL https://hyperterse.com/install | bash

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    core/framework/auth.go, line 109 expected = strings.TrimSpace(os.Getenv("HYPERTERSE_API_KEY"))

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    docs/bun.lock, line 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.
