CVE-2026-110975 Kruize CVE debrief

Who should care

Defenders responsible for Kruize Autotune deployments, especially those with network-accessible REST APIs, should assess exposure and verify the security of related monitoring stacks. This includes administrators, security teams, and DevOps personnel managing the Autotune service and its integrations.

Why it matters

CVE-2026-110975 exposes sensitive credentials in Kruize Autotune's REST API, allowing unauthenticated clients to harvest credentials for configured monitoring datasources. Defenders should verify exposure, assess related monitoring stack security, and implement authentication for the REST API.

• Credential harvesting and potential reuse for unauthorized access to monitoring stacks
• Elevation of privileges for attackers with network access to Kruize Autotune instances
• Potential lateral movement within monitoring environments
• Need for verification of exposure and remediation of vulnerable Kruize Autotune instances

Technical summary

The Kruize Autotune REST API does not implement an authentication layer, and its datasource configuration endpoints return sensitive credentials in cleartext. This allows unauthenticated clients with network access to harvest credentials and potentially reuse them to authenticate to the backing monitoring stack. The API's lack of authentication and authorization enables attackers to obtain sensitive information without any restrictions. Defenders should prioritize verifying exposure of Kruize Autotune instances and assess the security of related monitoring stacks.

Defensive priority

Defenders should prioritize verifying exposure of Kruize Autotune instances, especially those with network-accessible REST APIs, and assess the security of related monitoring stacks.

Recommended defensive actions

• Verify network exposure of Kruize Autotune instances and restrict access to the REST API
• Assess the security of related monitoring stacks and update credentials as necessary
• Implement authentication and authorization for the Kruize Autotune REST API
• Review and update datasource configurations to prevent unauthorized access
• Monitor for suspicious activity and implement compensating controls
• Perform a thorough review of affected systems and apply vendor patches
• Track exceptions and retest remediated assets to ensure vulnerability closure
