CyberRota Analysis
AI-GeneratedThe @backstage/plugin-kubernetes-backend package in Backstage versions prior to 0.21.10 is vulnerable due to an unsupported catalog cluster authentication mode, which may allow unauthorized catalog contributors to create or modify Kubernetes resource entities. This could lead to potential exposure of sensitive Kubernetes resources through the backend's local in-cluster identity, particularly affecting deployments utilizing catalog cluster discovery. Organizations using Backstage for developer portals should prioritize upgrading to version 0.21.10 to mitigate this risk.

Original NVD Description
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.
