## 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 (Insertion of Sensitive Information into Log File)
