Information disclosure via cross-user bearer-token cache reuse
Published Aug 11, 2026 · Updated Aug 11, 2026
Information disclosure in Red Hat Advanced Cluster Management for Kubernetes 2 allows remote authenticated users to read managed-hub search results. The getFederationConfig function stores one user's bearer token in a shared federation-configuration cache and reuses it for later users until expiration. Exploitation requires low-privileged authentication and the non-default FEATURE_FEDERATED_SEARCH setting, and exposes remote managed-hub search results without permitting changes.
