Executive Summary

This is a stored cross-site scripting (XSS) vulnerability in Leantime, a project management system. An authenticated user with project editor rights can inject malicious JavaScript into ticket status labels. The injected script executes in the browser of any user viewing the project dashboard, including managers and admins.

Detection Guidance

Check for unauthorized JavaScript in project dashboard status labels or user-controlled inputs. Inspect network traffic for requests to /app/Domain/Dashboard/Templates/show.blade.php with suspicious payloads. Review database entries for unencoded label names or classes.

Impact Analysis

The vulnerability allows attackers to execute arbitrary JavaScript in the context of other users' browsers. This can lead to session hijacking, privilege escalation, or full application compromise. Attackers could steal sensitive data or take control of accounts.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA requirements for data protection and access controls. Organizations using affected Leantime versions may face compliance violations and legal consequences.

Mitigation Strategies

Update Leantime to the latest version. Apply HTML encoding to status label outputs in the dashboard. Sanitize input during storage via the saveStatusLabels endpoint. Enforce server-side role validation for user creation and re-enable CSRF protection.
