Executive Summary

This vulnerability in JetBrains YouTrack before version 2026.2.18991 allows users with read-only permissions to access project settings that they should not be able to view. The issue stems from missing authorization checks.

Impact Analysis

An attacker with read-only access could exploit this to view sensitive project configurations, potentially exposing internal data or settings that could aid further attacks. The impact is limited as no data modification or system compromise occurs.

Compliance Impact

This vulnerability may violate compliance requirements that mandate strict access controls for sensitive data, such as GDPR's data protection principles or HIPAA's access controls. Unauthorized access to project settings could lead to regulatory penalties.

Mitigation Strategies

Update JetBrains YouTrack to version 2026.2.18991 or later to address the missing authorization issue for read-only users.
