NVD 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.

🚨High - Kibana Tag Management Path Traversal Leads to Privileged Deletion (CVE-2026-78592) Kibana tag management is vulnerable to path traversal where a low-privileged user with tag creation rights can craft a tag so an admin’s later action in the Tags UI resolves an unintended target path. With admin interaction, this can trigger deletion of privileged resources (e.g., admin accounts/org assets). No pre-auth exploitation. 👉Affected: Kibana (versions not specified)
Post summary
CVE‑2026‑78592 is a high‑severity path traversal flaw in Kibana tag management that can lead to privileged deletion when an admin interacts with a crafted tag. No existing exploitation code, patches, or real‑world attacks are reported.
