PERMISSION_SHELL_UNDECLARED INSTALL_REMOTE_SCRIPT

Why this grade

  • PERMISSION_SHELL_UNDECLARED Medium

    Runs shell commands that the manifest or description does not mention.

    src/package_version_check_mcp/main.py, line 178 result = subprocess.run(

  • 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-cd.yml, line 42 run: curl https://mise.run | 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.

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

    Concern

    requests shell access. No manifest field names shell or command execution. can delete files.

    PERMISSION_SHELL_UNDECLARED PERMISSION_DELETE_FILES

    src/package_version_check_mcp/main.py, line 178

    result = subprocess.run(

    src/package_version_check_mcp/get_latest_package_versions_pkg/fetchers/helm.py, line 396

    os.remove(tmp_file_extract.name)

    src/package_version_check_mcp/get_latest_tools_pkg/functions.py, line 51

    result = subprocess.run(

  • Install and update

    Serious

    install fetches a script from the network.

    INSTALL_REMOTE_SCRIPT

    .github/workflows/ci-cd.yml, line 42

    run: curl https://mise.run | sh

  • Network

    Concern

    can reach a host that is not written as a fixed address. can reach dl.k8s.io. The description does not name that host.

    NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST

    src/package_version_check_mcp/main.py, line 204

    - kubectl: Pin the version in a download URL called with curl or wget in a Dockerfile

    src/package_version_check_mcp/main.py, line 205

    (e.g., RUN curl -LO https://dl.k8s.io/release/v1.28.0/bin/linux/amd64/kubectl)

    src/package_version_check_mcp/main.py, line 207

    (e.g., curl -LO https://azurecliprod.blob.core.windows.net/releases/azure-cli-2.50.0.tar.gz)
