description

Apache Kylin versions 4.0.4 through 5.0.4 are affected by an OS command injection flaw. An attacker may be able to execute operating-system commands where an affected Kylin service is exposed to a public network.

Still under analysis: more detail becomes available as the pipeline runs.

mitigation

Upgrade Apache Kylin to version 5.0.5. Until upgrades are complete, restrict public network access to Kylin services.
