CVE-2025-71425 edgelesssys CVE debrief
CVE-2025-71425 debrief: Contrast before 1.8.1 Information Disclosure via Logging. The vulnerability allows unauthorized access to workload secrets via logging. Affected deployments should verify and upgrade to Contrast version 1.8.1 or later, review logging configurations, and restrict access to Kubernetes logs. This issue is particularly concerning as it exposes sensitive information to Kubernetes users with get or list permission on pods/logs and to anyone with read access to the Kubernetes log storage.

Who should care
Kubernetes administrators, security teams, and developers using Contrast should assess exposure and take steps to prevent sensitive information disclosure. This includes verifying and upgrading to Contrast version 1.8.1 or later, reviewing logging configurations, and restricting access to Kubernetes logs. Additionally, defenders should prioritize verifying and upgrading to Contrast version 1.8.1 or later, reviewing logging configurations, and restricting
Why it matters
CVE-2025-71425 is a high-severity vulnerability in Contrast that can lead to information disclosure via logging. Defenders should prioritize verifying and upgrading to Contrast version 1.8.1 or later, reviewing logging configurations, and restricting access to Kubernetes logs.
- Potential exposure of workload secrets to unauthorized Kubernetes users
- Increased risk of sensitive information disclosure due to logging configurations
- Need for verification and upgrade to Contrast version 1.8.1 or later
- Potential impact on confidentiality and integrity of workload secrets
Technical summary
The Contrast initializer logs the workload secret to stderr and Kubernetes logs when configured with CONTRAST_LOG_LEVEL set to info or debug, exposing workload secrets to unauthorized users. This issue affects deployments that do not customize the initializer log level. The vulnerability can be mitigated by verifying and upgrading to Contrast version 1.8.1 or later, reviewing logging configurations, and restricting access to Kubernetes logs. Affected deployments should assess exposure and take steps to prevent sensitive information disclosure.
Defensive priority
Defenders should prioritize verifying and upgrading to Contrast version 1.8.1 or later, reviewing logging configurations, and restricting access to Kubernetes logs.
Recommended defensive actions
- Verify and upgrade to Contrast version 1.8.1 or later
- Review and adjust logging configurations to prevent sensitive information disclosure
- Restrict access to Kubernetes logs and monitor for suspicious activity
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
- Review compensating controls for exposed systems while remediation is scheduled and verified
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
- Track exceptions, retest remediated assets, and close the item only after evidence is documented
