Remove hardcoded reverse shell payload to prevent remote code execution

[zeropath-ai-staging]

Summary

This script contains a hardcoded reverse shell payload, resulting in immediate remote code execution. Specifically, the index.js script (lines 3-11) constructs a shell command to connect back to attacker.example.com on port 4444 and executes it using exec(payload), which causes an attacker-controlled reverse shell to be established, granting unauthorized remote access to the system.

Vulnerability Details

• Vulnerability Class: Remote Code Execution (reverse shell execution)
• Severity: 10.0
• Affected File: stdin/index.js
• Vulnerable Lines: 3-11
