OpenClaw, a leading open-source AI assistant boasting over 215,000 stars on GitHub, has rolled out its latest version, 2026.2.23. This release is a significant leap forward, focusing on bolstering security measures while incorporating sophisticated AI functionalities.
Advanced Security Enhancements
The recent update tackles several security vulnerabilities, introducing crucial features such as support for Claude Opus 4.6. These enhancements cater to privacy-conscious users who operate AI gateways on platforms like macOS, Windows, and Linux.
One of the standout additions is the implementation of optional HTTP security headers, notably the Strict-Transport-Security protocol for HTTPS deployments. This feature, complete with validation, testing, and documentation, is designed to curb man-in-the-middle attacks.
Moreover, developers have improved session maintenance with the ‘openclaw sessions cleanup’ feature, which includes disk-budget controls and safer transcript handling to avert storage overflows and data breaches.
Security Policies and Fixes
In a pivotal change, the default browser SSRF policy now operates in ‘trusted-network’ mode. Users managing private networks must reconfigure settings, facilitated by the ‘openclaw doctor –fix’ tool.
Additional fixes address configuration and execution vulnerabilities. Sensitive dynamic keys like env.* are masked in configuration snapshots, ensuring data restoration without exposing sensitive information.
Execution security is tightened by demanding explicit approval for obfuscated commands. Furthermore, ACP client permissions now require trusted tool IDs with scoped read permissions to prevent unauthorized file access.
AI Innovations and System Improvements
On the AI front, OpenClaw introduces first-class support for the Kilo Gateway, with default integrations like kilocode/anthropic/claude-opus-4.6, enhancing authentication, onboarding, and cache management.
The Vercel AI Gateway now standardizes shorthand Claude references, and the tools/web_search feature adds the Moonshot ‘kimi’ provider with enhanced citation extraction capabilities.
OpenClaw’s media understanding is improved with native support for Moonshot video and refined execution processes for superior URL and header management. Agents benefit from per-agent parameter overrides, optimizing cache retention and minimizing prompt invalidations.
This version of OpenClaw, tagged by steipete, is a collaborative effort from numerous developers, reflecting its rapid growth as a secure AI hub for messaging platforms like WhatsApp and Telegram. With updates for Telegram polling, WhatsApp group policies, and specific provider adjustments, it ensures robust performance amid increasing ecosystem demands.
