CVE-2026-25253: OpenClaw RCE Vulnerability - Critical Security Alert
OpenClaw has a critical Remote Code Execution vulnerability. Learn how to patch it, or use a VPS to isolate your AI setup.
ā 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:
- Execute arbitrary commands on your system
- Access your local files
- 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
Option 2: Run in Docker (Recommended)
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:
| Provider | Specs | Monthly Cost | Best For |
|---|---|---|---|
| DigitalOcean | 4GB RAM, 2 vCPU | $24/mo | Beginners |
| Linode | 4GB RAM, 2 vCPU | $20/mo | Linux users |
| Hetzner | 4GB RAM, 2 vCPU | ā¬10/mo | Budget 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
-
Never run AI tools on your main machine
- Use a dedicated VPS
- Or use Docker with network isolation
-
Keep everything updated
- OpenClaw releases security patches frequently
- Subscribe to their security advisory feed
-
Monitor your logs
- Check for unusual activity
- Review OpenClaw logs regularly
-
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.
Summary
| Action | Status |
|---|---|
| Update OpenClaw | ā Fixes vulnerability |
| Run in Docker | ā Contains the damage |
| Use a VPS | ā Safest option |
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.
