Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
cilium-cli versions before 0.13.2 can remove etcd user permission enforcement when configuring cluster mesh, because an incorrect mount point overwrites the settings from the initContainer that sets up etcd users and permissions. An attacker who already holds a valid key and certificate for the affected etcd cluster could modify its state. Upgrade to cilium-cli 0.13.2. Clusters set up with the Cilium Helm chart are not affected.
