🔒 Security concerns Command Injection Risk: The implementation of the kill target in the Makefile uses shell commands that could potentially be exploited if the environment variables are not securely handled. This could allow an attacker to execute arbitrary commands on the system.

⚡ Key issues to review Command Injection Risk The use of shell commands in kill target (lines 291-297) with unsanitized input could lead to command injection vulnerabilities if the environment variables BACKEND_PORT and FRONTEND_PORT are not properly validated or are manipulated.
