Security Hardener

One-command OpenClaw security audit, scoring, and auto-remediation. Addresses CVE-2026-33579 and common misconfigurations. Scans for exposed API keys, weak file permissions, unauthenticated endpoints, unsafe plugin configs, insecure transport settings, and missing auth. Generates a 0-100 security score with severity-ranked findings and auto-fixes what it can. Use when asked to "harden my OpenClaw", "security audit", "am I secure", "fix my security", "security score", "check for exposed keys", "audit my agent", "CVE check", "lock down my instance", or when setting up a new OpenClaw installation and want to verify security posture before going live.

One-command security audit + auto-fix for OpenClaw. Generates a score, finds vulnerabilities, fixes what it can.

Quick Start

# Full audit — scan everything, show score + findings
python3 scripts/security-hardener.py audit

# Auto-fix all fixable issues (creates backup first)
python3 scripts/security-hardener.py fix

# Scan for exposed API keys only
python3 scripts/security-hardener.py keys

# Check auth configuration
python3 scripts/security-hardener.py auth

# Generate markdown report
python3 scripts/security-hardener.py report

Commands

audit — Full Security Audit

Runs all checks, produces a 0-100 security score:

• Auth check — Is authentication enabled? What type?
• Transport check — HTTPS/TLS configured? Certificates valid?
• Key exposure scan — API keys/tokens in config, memory, git history
• Permission check — File permissions on sensitive files (config, memory, soul)
• Plugin audit — Untrusted plugins, unsigned skills, risky permissions
• Network check — Bound interfaces, exposed ports, firewall status
• CVE check — Known OpenClaw CVEs against installed version

Options: --json for machine-readable output, --verbose for detailed findings.

fix — Auto-Remediate

Creates a timestamped backup, then fixes:

• Sets restrictive file permissions (600 for config, 700 for workspace)
• Removes API keys from memory/SKILL.md files (moves to .env)
• Enables auth if disabled
• Restricts bind address from 0.0.0.0 to 127.0.0.1
• Disables unsigned plugins

Options: --dry-run to preview fixes without applying, --backup-dir <path>.

keys — API Key Scanner

Searches config files, memory files, SKILL.md files, .env files, shell history, and git history for exposed secrets. Pattern library covers 40+ key formats (AWS, OpenAI, Anthropic, Stripe, etc.).

auth — Auth Configuration Check

Verifies authentication is properly configured:

• Gateway auth enabled and strong
• Session tokens rotated
• CORS policy appropriate
• Rate limiting configured

report — Markdown Report

Generates a security posture report suitable for compliance or auditing. Includes score, all findings, recommendations, and fix commands.

Scoring

Range	Rating	Meaning
90-100	🟢 Excellent	Production-ready
70-89	🟡 Good	Minor issues, fix recommended
50-69	🟠 Fair	Significant gaps, fix required
0-49	🔴 Critical	Unsafe for any exposure

Each finding has a severity (critical/high/medium/low) and a weight that affects the score.

CVE Coverage
