CVE-2026-78592 is a high-severity vulnerability rated 7.3/10 on the CVSS scale. 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. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
