CVE-2023-2878

Service account token disclosure via verbose logging

Published Jun 7, 2023 · Updated Feb 13, 2025

Information disclosure in Kubernetes Secrets Store CSI Driver before 1.3.3 allows local users to read service account tokens from logs. When TokenRequests is configured and verbosity is 2 or higher, the driver writes the csi.storage.k8s.io/serviceAccount.tokens value into its container log instead of excluding the credential from diagnostic output. Access to the driver logs is required; exposed tokens can be exchanged with external cloud providers to read secrets from cloud vaults.
