Security readout for executives and security teams
Plain-English summary
A permissions flaw can let a namespace administrator or similarly privileged user turn a Tempo service-account token into access to cluster-wide monitoring metrics. It affects deployments where the Jaeger UI Monitor Tab is enabled and the Tempo Operator grants the service account the cluster-monitoring-view role. The disclosed impact is sensitive-data exposure, not modification or service disruption.
Executive priority
Prioritize affected shared or sensitive OpenShift clusters, especially where namespace administration is delegated broadly. Treat this as a moderate confidentiality issue: exploitation needs prior privileges, but exposed cluster metrics may reveal operationally sensitive information. Patch during the next controlled maintenance window, accelerating where the prerequisite permissions are widely assigned.
Technical view
The Tempo Operator creates a ClusterRoleBinding to cluster-monitoring-view when Jaeger UI monitoring is enabled. A user able to create TempoStack resources and read Secrets in that namespace can obtain the Tempo service-account token and use its resulting cluster-wide metrics access. The issue is classified as CWE-200 with CVSS 3.1 score 4.3.
Likely exposure
Exposure requires a Tempo Operator-managed instance with Jaeger UI Monitor Tab enabled, plus a user holding both TempoStack creation and Secret-read permissions in its namespace. The bundle identifies affected Red Hat OpenShift distributed tracing 3 and 3.5.2 components. Exact fixed-version boundaries are not provided.
Exploitation context
The attack requires existing authenticated namespace privileges; it is not described as unauthenticated compromise. The disclosed result is read access to cluster metrics. The source bundle marks the CVE as absent from KEV and provides no evidence of active exploitation.
Researcher notes
The stated vector is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N. Validate the full authorization chain rather than token readability alone: feature enablement, generated ClusterRoleBinding, service-account credentials, and effective monitoring permissions. The bundle references an upstream pull request, but does not provide enough detail to state the exact code change or fixed upstream version.
Mitigation direction
- Apply updates identified in the relevant Red Hat security advisories.
- Check current Grafana Tempo Operator guidance for the corrected release.
- Disable Jaeger UI Monitor Tab functionality where operationally acceptable until remediation.
- Restrict TempoStack creation and Secret-read permissions to trusted administrators.
- Review unnecessary cluster-monitoring-view bindings created for Tempo service accounts.
Validation and detection
- Inventory Tempo Operator and Red Hat OpenShift distributed tracing versions.
- Identify TempoStack instances with Jaeger UI Monitor Tab enabled.
- Inspect Tempo service-account bindings to the cluster-monitoring-view role.
- Audit namespace roles combining TempoStack creation with Secret-read access.
- Confirm installed packages match vendor-remediated versions in applicable advisories.

Exposure of Sensitive Information to an Unauthorized Actor
Exposure of Sensitive Information to an Unauthorized Actor represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
