A flaw was found in the Trainer v2 TrainJob API. A user with permissions to create TrainJobs can exploit this by injecting "valueFrom.secretKeyRef" into environment variable definitions. This allows them to read and exfiltrate sensitive information (secrets) from the namespace, leading to a privilege escalation. This occurs when the TrainJob Role-Based Access Control (RBAC) is broader than the Secret read RBAC.
