Vulnerability Description

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (CWE-22) in Kibana can lead to the unauthorized deletion of privileged resources via Path Traversal (CAPEC-126).

Exploitation requires an administrator to interact with the affected interface.
