CVE-2020-10689

Authenticated workspace pod access via JWT proxy bypass

Published Apr 3, 2020 · Updated Aug 4, 2024

Missing authorization in Eclipse Che 7.8.x allows remote authenticated users to access another user's workspace pods via Kubernetes services. JWT proxy trust between workspace pods fails to restrict requests by workspace, so a pod can send unauthenticated requests to another user's Theia or machine-exec container when the target service name and namespace are known. Exploitation requires an authenticated user with high cluster-wide privileges and knowledge of the target pod location; successful access can expose or control that workspace.
