Attack-Flow Graph

Executive Summary

CVE-2025-37732 is a Cross-site Scripting (XSS) vulnerability in Kibana that occurs due to improper neutralization of input during web page generation in the integration package upload functionality. This allows an authenticated user with Management permissions for Fleet and Integrations to inject and render malicious HTML content in another user's browser. It bypasses a previous fix related to HTML injection. [1]

Impact Analysis

This vulnerability can allow an authenticated user with certain permissions to inject malicious HTML content that will be rendered in other users' browsers. This can lead to unauthorized actions, data theft, or session hijacking within the affected Kibana environment. The impact includes limited confidentiality and integrity loss but no availability impact. [1]

Detection Guidance

There are no specific detection commands or network/system detection methods provided for this vulnerability. Detection would generally involve verifying if your Kibana installation is within the affected versions and if unauthorized HTML injection attempts are observed, but no explicit commands are given.

Mitigation Strategies

The immediate mitigation step is to upgrade Kibana to a fixed version: 8.19.8, 9.1.8, or 9.2.2. No workarounds exist for users unable to upgrade, so applying the security update is essential to resolve the vulnerability. [1]
