What is CVE-2025-71423?
CVE-2025-71423 is a high-severity vulnerability in edgelesssys contrast, published on 27 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
Weakness: CWE-532
