OpenClaw AI Framework v2026.2.17 Released with Anthropic Model Support and Security Fixes

Technology Update: OpenClaw AI Framework v2026.2.17

OpenClaw has released version 2026.2.17, featuring enhancements such as support for Anthropic's Claude Sonnet 4.6 model. The update introduces expanded context windows and addresses critical security vulnerabilities related to credential theft and remote code execution.

The latest release includes opt-in support for Anthropic's 1-million-token context window via a beta header feature for Opus and Sonnet models, along with native integration of the Claude Sonnet 4.6 model. This update also contains forward-compatibility fallbacks to ensure seamless deployment across different configurations.

Despite ongoing patches, OpenClaw continues to face significant security challenges. CVE-2026-25253, a critical vulnerability patched in version 2026.1.29, allowed remote code execution through improper handling of authentication tokens and WebSocket connections. Security researchers have demonstrated how token leakage and Cross-Site WebSocket Hijacking can lead to system compromise.
