Summary

The Tempo Operator's gateway component failed to consistently apply namespace-scoped redaction on some query API response paths when query RBAC was enabled, allowing an authenticated user to read span attributes belonging to other tenants' namespaces.

This affects Red Hat OpenShift distributed tracing platform deployments with the Tempo Operator's query RBAC feature enabled prior to tempo-operator.v0.21.0-2, which corrects the gateway's authorization handling; the fix has already shipped to customers via RHSA-2026:33612. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).

Weakness: CWE-863. Affected Red Hat products: Red Hat OpenShift distributed tracing 3.10.1.

Red Hat fixing advisory: RHSA-2026:33612.

Is CVE-2026-62147 exploited?

No exploitation is reported in the sources VulniPulse tracks: CVE-2026-62147 is not in the CISA KEV catalog (checked ) and this advisory does not report exploitation. That is not proof the vulnerability cannot be exploited.

Mitigation checklist

Recommended fix / mitigation
  • There is no mitigation or workaround other than upgrading to tempo-operator.v0.21.0-2 (or later); until upgraded, administrators requiring strict namespace isolation of trace data should not rely on query RBAC alone and should consider restricting access to the Tempo query API at the network/route level as a temporary compensating control.
