The vulnerability stems from the agent granting excessive cluster-wide permissions within IBM Turbonomic Application Resource Management. A successful exploit allows an attacker who has compromised the operator or its associated service account to gain unrestricted read access to all secrets within the cluster. This vulnerability was reported on April 30, 2026, and poses a significant risk to organizations using the affected versions, potentially leading to complete cluster compromise. Defenders should prioritize patching and monitoring for unauthorized access to sensitive resources.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker gains initial access to the Kubernetes cluster, potentially through exploiting a vulnerability in a separate application or service running within the cluster, or via compromised credentials.\u003c/li\u003e\n\u003cli\u003eThe attacker identifies the IBM Turbonomic prometurbo agent and its associated service account within the compromised cluster.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the compromised service account or operator to interact with the Kubernetes API, exploiting the excessive cluster-wide permissions granted to the prometurbo agent.\u003c/li\u003e\n\u003cli\u003eThe attacker utilizes the unrestricted read access to enumerate and exfiltrate sensitive credentials stored as secrets within the cluster, including database passwords, API keys, and other sensitive information.\u003c/li\u003e\n\u003cli\u003eUsing the stolen credentials, the attacker escalates privileges by accessing other services and resources within the cluster, such as deploying malicious pods or modifying existing deployments.\u003c/li\u003e\n\u003cli\u003eThe attacker achieves persistence by creating or modifying service accounts, roles, and role bindings to maintain access to the cluster even if the initial point of compromise is remediated.\u003c/li\u003e\n\u003cli\u003eThe attacker moves laterally within the cluster, compromising additional nodes and workloads to expand their control and access to sensitive data.\u003c/li\u003e\n\u003cli\u003eThe attacker achieves full cluster compromise, gaining complete control over all resources and data within the Kubernetes environment.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eA successful exploitation of CVE-2026-6389 can lead to a full compromise of the Kubernetes cluster.
