Executive Summary

In JetBrains YouTrack before version 2026.1.14047, predefined search fields exposed all group names to any user, even if those groups were restricted by visibility permissions. This means unauthorized users could see the names of groups they were not supposed to access.

Impact Analysis

This vulnerability could allow attackers to enumerate internal group names, potentially aiding further attacks by revealing sensitive organizational structures or permissions. It may also lead to unauthorized access if group names are used in authentication or authorization processes.

Compliance Impact

This vulnerability could violate data protection requirements by exposing sensitive group names, which may include personal or confidential information. It undermines access control principles required by GDPR and HIPAA, potentially leading to compliance violations and legal consequences.

Mitigation Strategies

Update JetBrains YouTrack to version 2026.1.14047 or later to address the predefined search field visibility issue.
