Red Hat multicluster global hub is a set of components that enable you to import one or more hub clusters and manage them from a single hub cluster.

The podman tool manages pods, container images, and containers. It is part of the libpod library, which is for applications that use container pods. Container pods is a concept in Kubernetes. Security Fix(es): * podman: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application (CVE-2026-33810) * podman: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service (CVE-2026-56853) * podman: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal (CVE-2026-33818) * podman: golang net/url: Denial of Service from quadratic complexity in path resolution (CVE-2026-56860) * podman: Go: Denial of Service via XML decoding recursion depth issue (CVE-2026-56859) * podman: Go html/template: Cross-Site Scripting via pathological input (CVE-2026-56858) * podman: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages (CVE-2026-56862) * podman: golang.org/x/text: Denial of Service via invalid UTF-8 input (CVE-2026-56852) * podman: net/mail: Denial of Service via pathological email address parsing (CVE-2026-42499) * podman: Quadlet install --replace non-truncating write retains removed host-access directives (CVE-2026-19730) * podman: moby/go-archive: Arbitrary file write via link following in tar extraction (CVE-2026-17106) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in multicluster-global-hub. During a ManagedClusterMigration, the system incorrectly grants all managed hubs read access to a shared communication topic. This allows a compromised managed hub to intercept and collect sensitive bootstrap kubeconfigs, which contain API server tokens intended for other hubs. These tokens have an extended validity of approximately 9.86 years, significantly increasing the risk of unauthorized access and information disclosure to other managed clusters.

VolSync v0.15 is a Kubernetes operator that enables asynchronous replication of persistent volumes within a cluster, or across clusters. After deploying the VolSync operator, it can create and maintain copies of your persistent data. For more information about VolSync, see: https://docs.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.16/html/business_continuity/business-cont-overview#volsync or the VolSync open source community website at: https://volsync.readthedocs.io/en/stable/.
