GHSA-3W6P-8F82-GW8R Using JMSAppender in log4j configuration may lead to deserialization of untrusted data

Impact ClickHouse JDBC Bridge uses slf4j-log4j12 1.7.32, which depends on log4j 1.2.17. It allows a remote attacker to execute code on the server, if you changed default log4j configuration by adding JMSAppender and an insecure JMS broker. Patches The patch version 2.0.7 removed log4j dependency ...
