Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (CWE-22) in the Kibana Fleet feature can lead to the unauthorized deletion of resources via Path Traversal (CAPEC-126). A low-privileged user could cause a subsequent action taken by a higher-privileged user in the Fleet administration interface to act on an unintended target, resulting in the deletion of resources including accounts with elevated privileges.
