Summary

Apache Kylin from 4.0.0 through 5.0.4 contains a path-confinement bypass during metadata backup deletion (CWE-22). The check that should keep deletion inside the backup location can be bypassed. An unauthenticated remote attacker can exploit this over the network, with low impact on confidentiality, integrity and availability. Deployments directly exposed to the public network face the most risk.
