Backstage is an open framework for building developer portals. Prior to 0.21.8, the @backstage/plugin-kubernetes-backend package is affected by improper entity validation in deprecated kubernetes services endpoint. An authenticated user with Kubernetes read permissions could access Kubernetes workload data beyond their intended scope by supplying crafted entity data to the deprecated services endpoint. The exposure is limited to read-only access to Kubernetes object metadata across configured clusters. This issue is fixed in version 0.21.8.

### Impact An authenticated user with Kubernetes read permissions could access Kubernetes workload data beyond their intended scope by supplying crafted entity data to the deprecated services endpoint. The exposure is limited to read-only access to Kubernetes object metadata across configured clusters. ### Patches Patched in `@backstage/plugin-kubernetes-backend` version 0.21.8. ### Workarounds - Disable the deprecated `/services/:serviceId` route by deploying a custom Kubernetes router that omits it. - Restrict access to the `kubernetes.resources.read` permission to limit the set of users who can reach the endpoint.
