Summary

A flaw was found in Tempo Operator, where it creates a ServiceAccount, ClusterRole, and ClusterRoleBinding when a user deploys a TempoStack or TempoMonolithic instance.

This flaw allows a user with full access to their namespace to extract the ServiceAccount token and use it to submit TokenReview and SubjectAccessReview requests, potentially revealing information about other users' permissions.

While this does not allow privilege escalation or impersonation, it exposes information that could aid in gathering information for further attacks. Red Hat has evaluated this vulnerability and rated with a Moderate impact as the attacker is limited to read access and requires previous permissions to read the token and get access to the cluster metrics.

Red Hat severity: Moderate — CVSS 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N). Weakness: CWE-200.

Affected Red Hat products: Red Hat OpenShift distributed tracing 3.5.2; Red Hat OpenShift distributed tracing 3. Red Hat fixing advisory: RHSA-2025:3607, RHSA-2025:3740.
