CVE-2025-2786Network attack vector

Permission disclosure via overprivileged service account token

Published Apr 2, 2025 · Updated Aug 25, 2026

Sensitive information exposure in Tempo Operator before 0.15.3 allows remote authenticated users to inspect other users' permissions. With OpenShift tenancy enabled, reconciliation creates a gateway ServiceAccount and cluster bindings that grant TokenReview and SubjectAccessReview beyond the instance creator's permissions. Namespace-wide Secret access permits token extraction and authorization-metadata queries, but not impersonation or privilege escalation.
