Summary

Stolostron/multicluster-observability-addon: cross-namespace secret disclosure in multicluster-observability-addon via unvalidated configuration references

Details

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.
