CVE-2025-71425
Contrast before 1.8.1 Information Disclosure via Logging
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.

Contrast workload secrets leak to logs on INFO level
Impact
When the Contrast initializer is configured with a CONTRAST_LOG_LEVEL of info or debug, the workload secret is logged to stderr and written to Kubernetes logs.
Since info is the default setting, this affects all Contrast installations that don't customize their initializers' log level.
The following audiences are intended to have access to workload secrets (see https://docs.edgeless.systems/contrast/1.7/architecture/secrets#workload-secrets):
- Contrast Coordinator (can derive all workload secrets)
- Contrast Initializer (obtains only the secret configured in the manifest)
- Seedshare owner (can derive all workload secrets)
- Workload owner (can update manifests to obtain secrets)
This vulnerability allows the following parties unintended access to workload secrets issued by a Coordinator:
- Kubernetes users with
getorlistpermission onpods/logs. - Others with read access to the Kubernetes log storage (most notably, the cloud provider).
This vulnerability does not affect scenarios where workload secrets are not used by the application (directly or with secure persistence). Applications designed for workload owner exclusion can't use workload secrets and are thus unaffected.
Patches
N/A
Workarounds
This vulnerability can be mitigated by adding an environment variable CONTRAST_LOG_LEVEL=warn to the initializer after running contrast generate, and then running contrast generate again.
