CVE-2026-83495 Improper Privilege Management

No CVSS score yet. EPSS 0.1% estimated probability of exploitation activity in the next 30 days.

On this page
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.

Red Hat

Red Hat rates this Low.

Red Hat's statement

This issue has a Low impact as it affects Trainer v2, which is a Technology Preview feature in Red Hat OpenShift AI. Exploitation requires a user to have permissions to create TrainJobs while also having broader RBAC than allowed for Secret read access, enabling privilege escalation to exfiltrate secret values within the same namespace.

Red Hat's mitigation

To mitigate this vulnerability, ensure that the Role-Based Access Control (RBAC) for users creating TrainJobs is aligned with their Secret read permissions. Alternatively, restrict the `valueFrom.secretKeyRef` field within the validating webhook to an allowlist of permitted secret names. Review and adjust RBAC policies to prevent users from creating TrainJobs with broader access to Secrets than intended.
