OpenClaw versions prior to 2026.2.25 fail to enforce sender authorization checks for interactive callbacks including block_action, view_submission, and view_closed in shared workspace deployments. Unauthorized workspace members can bypass allowFrom restrictions and channel user allowlists to enqueue system-event text into active sessions.
