CVE-2026-106487Backstage: Unsupported catalog cluster authentication mode in kubernetes backend

backstage backstage; @backstage plugin-kubernetes-backend Veröffentlicht: (vor 1 Monat)

Beschreibung

Backstage is an open framework for building developer portals. Prior to 0.21.10, the @backstage/plugin-kubernetes-backend package is affected by unsupported catalog cluster authentication mode in kubernetes backend. Deployments using catalog cluster discovery may be affected when catalog contributors can create or modify kubernetes-cluster Resource entities. With the required endpoint permissions and pod RBAC, the backend can use its local in-cluster identity, potentially exposing Kubernetes resources readable by that identity. The credential is used only with the local in-cluster API endpoint and is not sent to the catalog-supplied endpoint. This issue is fixed in version 0.21.10.

Schwachstellentyp (CWE): CWE-441
