Description
OpenClaw (npm package `openclaw`) before 2026.7.1 fails to restrict owner-only infrastructure tools exposed through the chat.send endpoint. In Gateway deployments using authentication modes that honor caller identity and narrower operator scopes, a write-scoped non-owner caller can start a chat turn whose tool inventory includes the `gateway` and `cron` tools, causing the agent to invoke owner-only configuration or scheduling operations, including persistent state changes. Practical impact depends on the tools selected by the model and the caller's ability to steer the turn. Shared-secret token and password callers are treated as fully trusted operators under OpenClaw's security model and are outside the scope of this issue. The issue is fixed in 2026.7.1; as a workaround, restrict chat.send to administrators in identity-bearing deployments and remove `gateway` and `cron` from affected agent tool policies.
