### Impact `cilium-cli`, when used to configure cluster mesh functionality, can remove the enforcement of user permissions on the `etcd` store used to mirror local cluster information to remote clusters. Due to an incorrect mount point specification, the settings specified by the `initContainer` that configures `etcd` users and their permissions are overwritten when using `cilium-cli` to configure a cluster mesh. An attacker who has already gained access to a valid key and certificate for an `etcd` cluster compromised in this manner could then modify state in that `etcd` cluster. ### Patches This issue is patched in `cilium-cli` 0.13.2 All previous versions of `cilium-cli` are affected. Users who have set up cluster meshes using the Cilium Helm chart are not affected. ### Workarounds Use Cilium's [Helm charts](https://artifacthub.io/packages/helm/cilium/cilium) to create your cluster instead. ### Acknowledgements The Cilium community has worked together with members of Isovalent to prepare these mitigations. Special thanks to Marco Iorio for investigating and fixing the issue. ### For more information If you have any questions or comments about this advisory, please reach out on [Slack](https://docs.cilium.io/en/latest/community/community/#slack).
