      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Elastic Kibana&lt;/p&gt;
&lt;p&gt;Improper Limitation of a Pathname to a Restricted Directory (&amp;#39;Path Traversal&amp;#39;) (CWE-22) in the Kibana Fleet feature can lead to the unauthorized deletion of resources via Path Traversal (CAPEC-126).
