Executive Summary

CVE-2026-44228 is a stored Cross-Site Scripting (XSS) vulnerability in RT (Request Tracker) versions 6.0.0 to 6.0.2. It allows authenticated users with specific permissions to inject malicious JavaScript into user-controlled data fields. The injected script executes when other users view the affected page due to insufficient HTML escaping.

Detection Guidance

To detect this stored XSS vulnerability in RT, check the RT version installed on your system. Run: grep '^version' /opt/rt4/lib/RT.pm or similar path depending on installation. If the version is between 6.0.0 and 6.0.2, the system is vulnerable. Additionally, inspect user-modified fields like ticket subjects or custom fields for suspicious JavaScript code in the HTML source of affected pages.

Impact Analysis

This vulnerability could allow attackers to steal session cookies, perform actions on behalf of users, or deface the RT interface. It may also lead to unauthorized data access or manipulation if users interact with the injected scripts.

Compliance Impact

This stored XSS vulnerability could potentially violate GDPR and HIPAA by enabling unauthorized script execution that may access or manipulate sensitive user data. GDPR requires protection against unauthorized data access, while HIPAA mandates safeguards for protected health information. The vulnerability's impact depends on the data processed by RT and whether affected systems store regulated information.

Mitigation Strategies

Immediately upgrade RT to version 6.0.3 or later. If upgrading is not feasible, restrict content modification permissions to trusted users only. Regularly audit user-generated content for malicious scripts and monitor for unusual activity in RT logs.
