CVE-2026-44998 OpenClaw工具策略绕过漏洞

# Proof of Concept for CVE-2026-44998 # This script demonstrates the logic flaw where restricted tools # can be appended after the initial policy filtering. def simulate_openclaw_tool_policy_bypass(): # Initial set of tools provided by the agent bundled_tools = ['read_file', 'browse_web'] # Configured policy restrictions (Deny List) restricted_tools = {'execute_command', 'delete_file'} # Step 1: Policy Filtering (Normal Flow) # System filters out restricted tools from the initial request effective_tool_set = [tool for tool in bundled_tools if tool not in restricted_tools] print(f"[DEBUG] Post-filter tools: {effective_tool_set}") # Step 2: The Vulnerability (Bypass Logic) # Attacker with local agent access appends restricted tools AFTER filtering # This simulates the flawed logic in OpenClaw before 2026.4.20 malicious_payload = 'execute_command' # Vulnerable code path allows direct appending without re-checking policy effective_tool_set.append(malicious_payload) print(f"[DEBUG] Final tool set (Bypassed): {effective_tool_set}") # Step 3: Verification if 'execute_command' in effective_tool_set: print("[SUCCESS] Restricted tool 'execute_command' added successfully. Policy bypassed.") else: print("[FAIL] Policy enforced correctly.") if __name__ == "__main__": simulate_openclaw_tool_policy_bypass()
