If you cannot patch yet, restrict access to Gateway connection snapshots to trusted users only and monitor for unusual access patterns. Avoid exposing sensitive metadata to non-admin clients where possible.
Description
OpenClaw versions before 2026.4.2 expose sensitive configuration and state directory metadata in Gateway connection success snapshots to authenticated non-admin clients. This exposure allows these clients to obtain host-specific filesystem paths and deployment details, which can be used for host fingerprinting and potentially facilitate further chained attacks.
