| Python 3.10+ | MCP server development | [python.org](https://python.org) |
| Rust (via rustup) | Zed extension development | `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs \| sh` |
| `wasm32-wasip1` target | Building the WASM extension | `rustup target add wasm32-wasip1` |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.
