OpenClaw security audit and hardening
The ClawJacked vulnerability (CVE-2026-25253) exposed over 135,000 OpenClaw instances to remote command execution. If you have not audited your setup since then, your API keys, conversation data, and connected accounts may already be compromised. I find the holes and close them.
What the audit covers
Every audit systematically checks these six areas. Nothing is skipped, nothing is assumed safe.
Credential rotation
Every API key, bot token, and webhook secret in your setup is rotated and stored in a properly locked .env file. Old credentials are revoked, not just replaced.
.env audit and lockdown
Your environment variables are reviewed for leaked secrets, overly broad permissions, and insecure defaults. File permissions are set to owner-only read.
Network isolation
OpenClaw's WebSocket port, API endpoints, and management interfaces are restricted to localhost or trusted IPs only. No public exposure unless explicitly needed.
CVE patching
CVE-2026-25253 (ClawJacked) and any subsequent security advisories are patched and verified. Your OpenClaw version is updated to the latest secure release.
ClawHub skill review
Every installed ClawHub skill is audited for known vulnerabilities, excessive permissions, and suspicious network calls. Unaudited skills are flagged for removal.
Firewall configuration
UFW or iptables rules are configured to restrict inbound and outbound traffic to only the ports and destinations OpenClaw actually needs.
Common vulnerabilities found in audits
These are the issues I find most often. If you are running OpenClaw in production, there is a good chance at least one of these applies to you.
Plaintext API keys in config files
API keys for Claude, OpenAI, or other providers stored directly in openclaw.config.js instead of .env. Anyone with file access can read them, and they often end up in git history.
Exposed WebSocket port
OpenClaw's WebSocket interface bound to 0.0.0.0 instead of 127.0.0.1, making the management interface accessible from the public internet with no authentication.
Unaudited ClawHub skills
Third-party skills installed from ClawHub without reviewing their source code. Some skills have been found to exfiltrate conversation data or inject unauthorized API calls.
No access control on agent endpoints
The REST API and WebSocket endpoints have no authentication tokens or IP restrictions, allowing anyone who discovers the port to send commands to your agent.

Do not wait for a breach to find out
Most OpenClaw instances I audit have at least two critical vulnerabilities. A one-hour review now prevents weeks of damage control later.
