HIGH

Makefile/script pipes remote content to shell

repo/README.zh-CN.md:120

        # 如果没有安装 uv，请先安装:
        # curl -LsSf https://astral.sh/uv/install.sh | sh
        # source $HOME/.cargo/env # 或者重启你的 shell

Why was this flagged?

A script or Makefile pipes content from a remote URL directly into a shell (curl | sh or wget | bash). This is inherently dangerous because the remote content can change at any time, and the command runs with the current user's permissions. Rated HIGH because it requires manual execution (unlike install hooks) but still executes arbitrary remote code.
