CVE-2025-71423— Edgelesssys Contrast before 1.12.2 Workload Secrets Information Disclosure

Quick assessment

Affected
edgelesssys contrast
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

EdgelessSys Contrast 是一个用于 Kubernetes 的机密计算运行时。在 1.9.0 至 1.12.2 版本（不含 1.12.2）中，初始化程序会将包含工作负载密钥的完整 NewMeshCert 响应以 INFO 级别记录到标准输出。因此，任何对 pod/logs 具有 get 或 list 权限的 Kubernetes 用户都可以获取这些工作负载密钥。由于这些工作负载密钥用于加密存储和 Vault 集成，因此它们也被视为已泄露。此问题是 GHSA-h5f8-crrq-4pw8 的回归漏洞。

Vulnerability Title
Edgelesssys Contrast before 1.12.2 Workload Secrets Information Disclosure
Source: CVE Program / CVE List V5
Vulnerability 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.
