OpenClaw 2026.2.23 Hardens Security While Adding Claude Opus 4.6 Support
3 min. read 
Published on
OpenClaw v2026.2.23 brings enterprise-grade security fixes to its 215,000+ GitHub star AI assistant. New HTTP security headers, SSRF protection, and credential redaction block prompt injection and data leaks. Claude Opus 4.6, Moonshot Kimi video analysis, and Kilo Gateway integration expand capabilities across macOS, Windows, Linux.
Privacy-focused users gain Strict-Transport-Security headers for direct HTTPS deployments. Comprehensive validation and documentation ship with HSTS implementation. Man-in-the-middle attacks face immediate blocking.
Session cleanup introduces disk budget controls preventing storage overflows. Transcript handling eliminates local data accumulation risks completely. Production deployments run indefinitely without cleanup failures.
Breaking change defaults browser SSRF policy to trusted-network mode. Private network users run openclaw doctor --fix for seamless migration. Legacy allowPrivateNetwork configs auto-convert safely.
Configuration snapshots redact env. and skills.env. keys automatically.** Restore functionality preserved while blocking exposure in logs and diagnostics. OTEL telemetry scrubs API keys before export.
Security Hardening Table
| Fix | Threat Blocked | Impact |
|---|---|---|
| SSRF Policy | Internal network scans | Defaults to trusted-network |
| Config Redaction | API key leaks | env.* hidden in snapshots |
| Command Approval | Obfuscated injection | Manual approval required |
| Skills XSS | Stored cross-site scripting | HTML input escaping |
| OTEL Redaction | Telemetry exposure | Keys scrubbed pre-export |
Skills packaging rejects symlink escapes and XSS-vulnerable gallery prompts. ACP client demands trusted tool IDs with scoped read permissions only.
