How to fix?

Upgrade org.apache.flink:flink-metrics-jmx to version 1.9.3, 1.10.1 or higher.


org.apache.flink:flink-metrics-jmx is an open-source stream-processing framework developed by the Apache Software Foundation.

Affected versions of this package are vulnerable to Information Exposure. When running a process with an enabled JMXReporter, with a port configured via metrics.reporter.<reporter_name>.port, an attacker with local access to the machine and JMX port can execute a man-in-the-middle attack using a specially crafted request to rebind the JMXRMI registry to one under the attacker's control. This compromises any connection established to the process via JMX, allowing extraction of credentials and any other transferred data.
