CVE-2026-83495
📛 CVE Title
Trainer: trainer: trainjob env passthrough enables valuefrom.secretkeyref injection for namespace secret exfiltration
Description
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.
