To prevent a vulnerability when it is run near the clickhouse-server, we will limit the paths of libraries to a location, provided in the configuration. This vulnerability was found with the ClickHouse Bug Bounty Program by Arseniy Dugin. #75954 (Alexey Milovidov).entrypoint.sh. A long-postponed improvement was suggested in #50724. Added switch --users to clickhouse-extract-from-config to get values from the users.xml. #75643 (Mikhail f.
