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

INSTALL_REMOTE_SCRIPT

Why this grade

  • INSTALL_REMOTE_SCRIPT Medium

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    .github/workflows/ci.yml, line 27 run: curl -sSfL https://raw.githubusercontent.com/golangci/golangci-lint/HEAD/install.sh | sh -s -- -b "$(go env GOPATH)/bin" v2.13.1

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

    cmd/mcpd/stdio_test.go, line 28

    cmd := exec.Command(binary)

    cmd/mcpd/stdio_test.go, line 72

    out, err := exec.Command("go", "build", "-o", binary, ".").CombinedOutput()

  • Install and update

    Serious

    install fetches a script from the network.

    INSTALL_REMOTE_SCRIPT

    deploy/README.md, line 144

    curl -fsSL https://tailscale.com/install.sh | sh

    .github/workflows/ci.yml, line 27

    run: curl -sSfL https://raw.githubusercontent.com/golangci/golangci-lint/HEAD/install.sh | sh -s -- -b "$(go env GOPATH)/bin" v2.13.1

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

    cmd/ingest/main.go, line 346

    err = fetch(ctx)

    internal/ingest/thumbs.go, line 135

    raw, err := t.fetch(ctx, sourceURL)

    internal/streeteasy/client.go, line 169

    out, err := fetch(ctx, areas, q, band, page)

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_ENV_READ SECRETS_PATH_DOTENV

    internal/config/config.go, line 85

    AccessKey: strings.TrimSpace(os.Getenv("S3_ACCESS_KEY")),

    Connect a client (`.env` is read by compose, not your shell, hence the export):

    set -a; . ./.env; set +a

    cp env.example .env
