Command Injection Vulnerability in AI-Generated Code

Claude Code generated backend code that constructs shell commands or system calls by concatenating user input directly into the command string. An attacker can inject additional commands by including shell metacharacters like semicolons, pipes, or backticks in their input.

This is especially dangerous in Node.js or Python backends where child_process.exec() or os.system() are used with string interpolation. The generated code may look correct at first glance but opens a direct path to remote code execution on your server.

You might discover this during a code review, a penetration test, or after an attacker has already exploited it to read files, install backdoors, or exfiltrate data from your server.
