Technical analysis, exploit verification, and patch instructions for CVE-2026-10609 impacting redhat cluster_logging_operator. Evaluated with CVSS Base Score of 6.8 (MEDIUM).

Original NVD Description

Source: NIST NVD
A missing authorization flaw was found in the OpenShift Cluster Logging Operator. The operator creates and forwards ServiceAccount tokens to output destinations without verifying that the ClusterLogForwarder creator has permission to use those credentials, allowing a delegated editor to exfiltrate SA tokens and escalate privileges.
