Path Traversal in Kibana Leading to Privileged Resource Deletion

Publication date: 2026-09-01

Last updated on: 2026-09-01

Assigner: Elastic

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.

Attack-Flow Graph

Executive Summary

CVE-2026-78592 is a Path Traversal vulnerability (CWE-22) in Kibana that allows a low-privileged user with tag creation privileges to manipulate administrative actions via the tag management interface. This can lead to the unauthorized deletion of privileged resources such as administrative accounts and other organizational assets. Exploitation requires an administrator to interact with the affected interface.

Detection Guidance

To detect this vulnerability, check if your Kibana version is within the affected range (7.11.0-7.17.29, 8.0.0-8.19.15, or 9.0.0-9.4.1). Run: curl -s http://localhost:5601/api/status | grep version. If the version is outdated, the system is vulnerable.

Impact Analysis

This vulnerability can result in the deletion of critical resources like administrative accounts, disrupting operations and causing data loss. Attackers could leverage it to compromise system integrity and availability, potentially leading to unauthorized access or service disruptions.

Compliance Impact

This vulnerability could lead to unauthorized data deletion or access, violating GDPR's integrity and availability principles or HIPAA's safeguards for protected health information. Non-compliance risks include fines, legal penalties, and reputational damage.

Mitigation Strategies

Upgrade Kibana to a patched version (8.19.16, 9.3.5, or 9.4.2) immediately. If upgrading is not possible, restrict access to the tag management interface and monitor for unusual administrative actions.
