# OpenClaw Security Hardening Checklist: How to Audit and Lock Down Your Deployment

> 40,000+ OpenClaw instances exposed online with public RCE exploits. Three CVEs (CVSS 7.8–8.8) — here's how to check and fix your deployment.

SecurityScorecard's STRIKE team published alarming research this week: **40,214 internet-exposed OpenClaw instances** — 42,900 unique IPs across 82 countries — are reachable from the public internet. Of those, **35.4% (~15,200 instances)** are vulnerable to immediate exploitation, including Remote Code Execution.

Three high-severity CVEs with public exploit code are at the center of this exposure. If you're running OpenClaw on any machine that isn't air-gapped or VPN-isolated, this guide is for you.

## The Three CVEs You Need to Know

### CVE-2026-25253 — One-Click RCE via WebSocket Token Theft (CVSS 8.8)
**Affects:** Versions before 2026.1.29

The OpenClaw gateway exposes a WebSocket endpoint for real-time agent communication. In versions before 2026.1.29, authentication tokens could be stolen via a crafted webpage — a single browser visit to a malicious site could hand an attacker full RCE on the gateway process.

**Fix:** Update to v2026.2.1 or later.

### CVE-2026-25157 — SSH Command Injection on macOS (CVSS 7.8)
**Affects:** macOS deployments only

A command injection vulnerability in the SSH transport layer allows an attacker with network access to inject arbitrary shell commands through malformed SSH connection strings. macOS-specific path handling makes this exploitable in ways that don't trigger on Linux.

**Fix:** Update to v2026.2.1 or later. If you can't update immediately, disable SSH-based agent features.

### CVE-2026-24763 — Docker Sandbox Escape via PATH Manipulation (CVSS 7.8)
**Affects:** Deployments using Docker sandbox mode

The Docker sandbox intended to isolate agent execution can be escaped by an attacker who controls PATH environment variables during container init. This grants host-level access.

**Fix:** Update to v2026.2.1 or later. Verify your Docker socket is not mounted read-write to agent containers.

## Step-by-Step Hardening Checklist

Work through these in order. Each step is actionable and most take less than five minutes.

### Step 1: Check Your OpenClaw Version

```bash
openclaw --version
```

You should be on **v2026.2.1 or later**. If you're behind:

```bash
npm update -g openclaw
```

Or follow your package manager's update path. Confirm the version after updating.

### Step 2: Audit Your Gateway Binding

The root cause for the majority of exposed instances is a default that binds the gateway to `0.0.0.0:18789` — meaning it listens on *all* network interfaces, including public ones.

Check your current binding:

```bash
openclaw gateway status
```

Look for the `bind` field. If it says `0.0.0.0`, you're exposed.

Fix it by editing your OpenClaw config (typically `~/.openclaw/config.json` or `~/.openclaw/config.yaml`):

```json
{
  "gateway": {
    "bind": "127.0.0.1",
    "port": 18789
  }
}
```

Restart the gateway:

```bash
openclaw gateway restart
```

Verify the fix:

```bash
ss -tlnp | grep 18789
```

You should see `127.0.0.1:18789`, not `0.0.0.0:18789`.

### Step 3: Enable Authentication

Default OpenClaw installs may not have auth enabled. Check:

```bash
openclaw gateway status | grep auth
```

To enable authentication:

```bash
openclaw gateway config --auth-enabled true --mfa true
```

Or set in your config file:

```json
{
  "gateway": {
    "auth": {
      "enabled": true,
      "mfa": true
    }
  }
}
```

### Step 4: Add a VPN, Tailscale, or Cloudflare Tunnel

Even with `127.0.0.1` binding, if you need remote access to your OpenClaw instance, **don't open port 18789 to the internet directly**. Use one of these:

**Tailscale (recommended for most users):**
```bash
curl -fsSL https://tailscale.com/install.sh | sh
tailscale up
```

Then access your gateway at `http://100.x.x.x:18789` (your Tailscale IP) rather than your public IP.

**Cloudflare Tunnel:**
```bash
cloudflared tunnel create openclaw
cloudflared tunnel route dns openclaw openclaw.yourdomain.com
```

This gives you HTTPS + Cloudflare's DDoS protection without exposing any port directly.

### Step 5: Verify Docker Sandbox Configuration (CVE-2026-24763)

If you use Docker sandbox mode for agent execution:

```bash
docker inspect <your-openclaw-agent-container> | grep -A5 Mounts
```

Ensure the Docker socket (`/var/run/docker.sock`) is **not** mounted into agent containers. If it is, remove it from your compose file or container config.

Also verify no writable PATH overrides exist:

```bash
docker inspect <container> | grep -i path
```

### Step 6: Check the STRIKE Dashboard

SecurityScorecard has a live dashboard that tracks exposed OpenClaw instances, updated every 15 minutes:

👉 **[declawed.io](https://declawed.io/)** — search for your IP or organization to see if you appear in their scan.

If you appear there after applying these fixes, wait 30 minutes and recheck. The dashboard updates frequently.

## Quick Reference: Exposure Matrix

| CVE | Severity | Affected Versions | Fix Version | Exploitation |
|-----|----------|------------------|-------------|--------------|
| CVE-2026-25253 | CVSS 8.8 | < 2026.1.29 | v2026.2.1+ | Public exploit available |
| CVE-2026-25157 | CVSS 7.8 | macOS only | v2026.2.1+ | Network access required |
| CVE-2026-24763 | CVSS 7.8 | Docker sandbox | v2026.2.1+ | PATH manipulation |

## Don't Stop at Patching

The SecurityScorecard research makes a deeper point worth sitting with: **agentic AI tools are uniquely dangerous when exposed**. Unlike a standard web app, a compromised OpenClaw instance doesn't just leak data — it can autonomously execute actions across all connected systems, send messages, deploy services, and modify files at the direction of an attacker.

Patch, yes. But also audit your agent permissions, rotate credentials, and treat your OpenClaw instance with the same posture you'd treat a root shell.
