A flaw was found in odh-dashboard in Red Hat OpenShift AI. The backend-for-frontend route GET /api/nim-serving/:nimResource reads Kubernetes Secrets using the dashboard service account and returns the full Secret object, including .data, without an authorization check. Any authenticated dashboard user can retrieve the cluster NVIDIA NGC API key Secret (apiKeySecret) and the NIM image pull secret (nimPullSecret). Create and delete of the same NIM credential are admin-gated; the read path is not. This is missing authorization (CWE-862) and insufficiently protected credentials (CWE-522). It is distinct from CVE-2026-5483 (service-account token leak in the Kubernetes client response wrapper on the same route) and CVE-2026-16456 (odh-model-controller cross-namespace confused deputy).

Reported privately by Dmitry Maranik (Sectum AI) via PSIRTSUPT-22896. Confirmed by source review of opendatahub-io/odh-dashboard at HEAD (backend/src/routes/api/nim-serving/index.ts). Not reproduced against a live RHOAI + NGC deployment. Preconditions: authenticated dashboard access and a NIM Account CR with the referenced Secrets present.
