install-makefile-curl
HIGHMakefile/script pipes remote content to shell
package/scenarios/install-curl-pipe-sh/README.md:9
The script runs `curl https://example.com/setup.sh | sh`. An attacker who compromises the server or intercepts the connection can replace the script with malicious code that executes with the current user's privileges.
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.

INSTALL-001 detects `curl ... | sh`, `curl ... | bash`, `wget ... | sh`, and similar patterns in shell scripts and Dockerfiles.
