What is CVE-2025-71425?
CVE-2025-71425 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
Contrast (Edgeless Systems) before 1.8.1 logs the workload secret to stderr, and thus to Kubernetes logs, when the Contrast initializer is configured with CONTRAST_LOG_LEVEL set to info or debug. Because info is the default, all installations that do not customize the initializer log level are affected. This exposes workload secrets — normally accessible only to the Contrast Coordinator, the initializer, the seedshare owner, and the workload owner — to Kubernetes users with get or list permission on pods/logs and to anyone with read access to the Kubernetes log storage, such as the cloud provider. Deployments that do not use workload secrets are unaffected.
Weakness: CWE-532
