CVE-2026-83495 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It affects Red Hat OpenShift AI (RHOAI); no fixed version is listed yet.

## Summary

The Trainer v2 TrainJob API lets a user who can create TrainJobs read and exfiltrate secrets from their namespace by injecting `valueFrom.secretKeyRef` into environment variable definitions, which can lead to privilege escalation. The flaw applies when TrainJob RBAC is broader than Secret read RBAC.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- rhoai/odh-trainer-rhel9: version range not reported

## 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.
