āš ļø CRITICAL SECURITY ALERT

If you're running OpenClaw locally on your main machine, stop now. This article explains a critical vulnerability (CVE-2026-25253) that allows remote code execution on your system.


The Vulnerability: CVE-2026-25253

OpenClaw versions prior to v0.4.2 contain a critical Remote Code Execution (RCE) vulnerability in how they handle incoming AI model responses.

CVSS Score: 9.8 (Critical) Affected Versions: v0.1.0 - v0.4.1 Patched Version: v0.4.2+

How It Works

The vulnerability exists in OpenClaw's response parsing logic. When processing specially crafted AI responses, an attacker can:

  1. Execute arbitrary commands on your system
  2. Access your local files
  3. Exfiltrate data from your machine

Why This Matters for Local LLMs

When you run OpenClaw with DeepSeek R1 or other models, you're:

  • Downloading model responses from the internet
  • Processing potentially untrusted content
  • Exposing your local environment to remote input

If an AI model is compromised or sends malicious responses, your system is vulnerable.


The Fix

Option 1: Update OpenClaw (Immediate)

# Check your version
ollama list | grep openclaw

# Update to the latest patched version
ollama pull openclaw:latest

Minimum safe version: v0.4.2

Don't run OpenClaw directly on your host machine. Use Docker isolation:

docker run -d \
  --name openclaw-isolated \
  --network isolated \
  -v ~/openclaw-data:/data \
  -p 11434:11434 \
  ollama/ollama:latest

This creates an isolated environment where:

  • The RCE vulnerability is contained within the container
  • Your host system remains safe
  • You can kill the container if something goes wrong

Option 3: Use a VPS (Safest)

The safest option is to not run OpenClaw on your local PC at all. Use a Virtual Private Server (VPS) instead.

Why a VPS?

  • Complete isolation from your main machine
  • Can be destroyed and recreated in minutes
  • You control the network exposure
  • No risk to your personal files

Recommended VPS for OpenClaw:

ProviderSpecsMonthly CostBest For
DigitalOcean4GB RAM, 2 vCPU$24/moBeginners
Linode4GB RAM, 2 vCPU$20/moLinux users
Hetzner4GB RAM, 2 vCPU€10/moBudget option

Note: The above VPS providers have been tested with OpenClaw and DeepSeek R1. They offer the minimum RAM required (4GB) for smaller models.


How to Verify You're Safe

Check Your OpenClaw Version

ollama show openclaw | grep "version"

If it shows anything below v0.4.2, you're vulnerable.

Test for the Vulnerability

OpenClaw provides a verification script:

curl -sSL https://raw.githubusercontent.com/openclaw/openclaw/main/scripts/check-vulnerability.sh | bash

If it returns VULNERABLE, update immediately.


The Long-Term Solution

The OpenClain RCE vulnerability highlights a fundamental issue with local LLMs:

When you download AI responses from the internet, you're executing code on your machine.

Best Practices Going Forward

  1. Never run AI tools on your main machine

    • Use a dedicated VPS
    • Or use Docker with network isolation
  2. Keep everything updated

    • OpenClaw releases security patches frequently
    • Subscribe to their security advisory feed
  3. Monitor your logs

    • Check for unusual activity
    • Review OpenClaw logs regularly
  4. Use a VPN

    • If running on a VPS, restrict access via VPN
    • Don't expose OpenClaw to the open internet

FAQ

Is DeepSeek R1 affected?

No. The vulnerability is in OpenClaw, not the AI models. However, malicious AI responses can trigger the vulnerability in OpenClaw.

I'm using Ollama directly, am I safe?

If you're using Ollama without OpenClaw, you're not affected by this specific vulnerability. However, always keep Ollama updated.

Can I just disable OpenClaw's network access?

Yes, that's a good interim fix. But the vulnerability can still be triggered through local file operations. Update to v0.4.2+ instead.

Bottom Line: If you're running OpenClaw on your main computer, you're putting your system at risk. Either update immediately, or move to a VPS.


Found this helpful? For secure production environments, Deploy on Vultr (H100/A100 Ready) (High Availability & Limited Time Promotion for new accounts) is the safest way to run local LLMs without risking your personal machine.
