The OpenClaw Prometheus diagnostics plugin (@openclaw/diagnostics-prometheus) before version 2026.9.3 does not enforce the operator.read scope on its authenticated metrics endpoint. In deployments using an identity-bearing Gateway authentication mode such as trusted-proxy, a caller whose effective role has no read scope can retrieve the diagnostics document even though ordinary read methods reject the same identity, disclosing operational metrics to an authenticated profile intentionally limited below read access. Shared-secret Gateway callers already hold the documented full operator scope and are not affected.
The issue is fixed in 2026.9.3; as a workaround, disable the Prometheus endpoint or ensure every identity that can reach it is intended to hold operator.read.
