CVE-2025-11393 is a vulnerability in the runtimes-inventory-rhel8-operator component of Red Hat Lightspeed (formerly Insights) for Runtimes 1.0. The root cause is an internal proxy component that is incorrectly configured to attach the cluster's main administrative credentials to all commands it processes, rather than limiting this to specific authorized reports. This misconfiguration creates a 'confused deputy' scenario, where the proxy inadvertently grants elevated privileges to commands issued by standard users within the cluster. Consequently, any user with standard cluster access can leverage this flaw to execute commands on the management platform with full cluster administrator rights. This can lead to unauthorized configuration changes, status modifications, or other administrative actions on the cluster managed via the Red Hat platform. The vulnerability is remotely exploitable by an authenticated user with low privileges and does not require user interaction. The CVSS v3.1 base score is 8.7, reflecting high confidentiality and integrity impacts, partial scope change, and low attack complexity. Although no exploits are currently known in the wild, the flaw poses a significant risk to clusters using this product, especially in environments with multiple users and complex administrative setups. The vulnerability was publicly disclosed on December 15, 2025, and no patch links are currently provided, indicating that remediation may be pending or in progress.

The impact of CVE-2025-11393 is substantial for organizations running Red Hat Lightspeed for Runtimes 1.0 in their cluster environments. By allowing any standard user to escalate privileges to full cluster administrator rights, attackers or malicious insiders can make unauthorized changes to cluster configurations, potentially disrupting operations or compromising sensitive data. The confidentiality and integrity of the cluster management platform are severely affected, as attackers can manipulate configurations, deploy malicious workloads, or disable security controls. Although availability is not directly impacted, the unauthorized changes could indirectly cause service disruptions or degrade cluster performance. This vulnerability undermines the principle of least privilege and trust boundaries within the cluster, increasing the risk of insider threats and lateral movement. Organizations relying on this Red Hat product for runtime management and insights face increased risk of compromise, data breaches, and operational impact if this flaw is exploited.

To mitigate CVE-2025-11393, organizations should immediately audit user permissions within their clusters to ensure that only trusted users have access to the runtimes-inventory-rhel8-operator component. Restrict standard user capabilities to the minimum necessary and consider implementing role-based access controls (RBAC) to limit command issuance. Monitor cluster management platform logs for unusual command activity that may indicate exploitation attempts. Since no official patches are currently available, coordinate with Red Hat support for any interim fixes or configuration guidance. Consider isolating the proxy component or deploying network segmentation to limit access to the management platform. Implement multi-factor authentication and strong identity verification for cluster users to reduce the risk of compromised credentials. Once a patch is released, prioritize its deployment across all affected environments. Additionally, conduct regular security assessments and penetration testing focused on cluster management components to detect similar privilege escalation vectors.
