v2026.6.6 has fully implemented sandbox boundary isolation, transcript separation, and sensitive image anonymization, and has also integrated Claude Fable 5. The security community is ecstatic.

CoinWorld News reports that OpenClaw has released the v2026.6.6 major update, fully tightening the boundaries of the security sandbox and integrating multiple cutting-edge large-model features. The new version delivers major upgrades targeting issues such as AI agent privilege escalation and privilege bypass vulnerabilities, covering multiple dimensions including transcripts isolation, sandbox binding restrictions, and host environment variable inheritance. In terms of approval mechanisms, it introduces a hard limit of “fail closed” on timeouts to prevent sensitive information leakage, prohibits the pseudo-transmission of codex/harmony protocol artifacts, and performs desensitization on sensitive images. Additionally, OpenClaw achieves deep integration with Claude Fable 5’s adaptive thinking and adds OpenRouter.
