Upstream source 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). A low-privileged user holding tag creation privileges could cause a subsequent administrative action in the tag management interface to act on an unintended target, resulting in the deletion of privileged resources including administrative accounts and other organizational assets. Exploitation requires an administrator to interact with the affected interface.
