CVE-2025-71423 (CVSS 7.3)

Description

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.
