### Security and permissions {#security-and-permissions}

* `SYSTEM RESTART REPLICAS` will only restart replicas in the databases where you have permission to `SHOW TABLES`. Previously the query led to the wakeup of tables in the Lazy database, even without access to that database, while these tables were being concurrently dropped. [#83321](https://github.com/ClickHouse/ClickHouse/pull/83321) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Functions `azureBlobStorage`, `deltaLakeAzure`, and `icebergAzure` have been updated to properly validate `AZURE` permissions. All cluster-variant functions (`-Cluster` functions) now verify permissions against their corresponding non-clustered counterparts. Additionally, the `icebergLocal` and `deltaLakeLocal` functions now enforce `FILE` permission checks.

* Functions `azureBlobStorage`, `deltaLakeAzure`, and `icebergAzure` have been updated to properly validate `AZURE` permissions. All cluster-variant functions (`-Cluster` functions) now verify permissions against their corresponding non-clustered counterparts. To prevent permission errors, make sure users invoking the `-Cluster` functions have the appropriate privileges (e.g., `GRANT S3 ON *.* TO user`). Additionally, the `icebergLocal` and `deltaLakeLocal` functions now enforce `FILE` permission checks.
