CVE-2026-89060
גבוהה 7.7
תיאור (מקור, אנגלית)
A cross-namespace authorization flaw in multicluster-observability-addon allows a user with permission to modify a managed cluster’s ManagedClusterAddOn configuration to reference ClusterLogForwarder or OpenTelemetryCollector resources outside the permitted namespace. If those resources reference Secrets, the add-on may copy the referenced Secrets to the attacker-controlled managed cluster.
