CVE-2025-71423: Edgelesssys Contrast is a confidential-computing runtime for Kubernetes
CVE-2025-71423 analysis covering impact, affected products, versions, remediation, and cross-checked defender guidance.
CVE-2025-71423 is a vulnerability published by NVD on 9/27/2026.
What happened
Edgelesssys Contrast is a confidential-computing runtime for Kubernetes. In versions 1.9.0 before 1.12.2, the initializer logs the full NewMeshCert response — which contains the workload secret — to standard output at INFO level. As a result, workload secrets are exposed to any Kubernetes user with get or list permission on pods/logs. Because workload secrets are used for encrypted storage and Vault integration, those must also be considered compromised. This is a regression of GHSA-h5f8-crrq-4pw8.
