CVE-2026-5483Network attack vector

Service account token disclosure via NIM endpoint

Published Apr 10, 2026 · Updated Apr 10, 2026

Sensitive-data exposure in Red Hat OpenShift AI allows remote authenticated users to obtain Kubernetes service account tokens. The /api/nim-serving/:nimResource NodeJS route returns the full Kubernetes client response without removing the dashboard's service account token. Exploitation requires dashboard access, an existing NIM Account custom resource, and its referenced secret; resulting Kubernetes access is bounded by the exposed account's RBAC permissions.
