Executive Summary

Kimai before version 2.62.0 has an authorization bypass flaw in the QuickEntry controller. Authenticated users with view_other_timesheet and edit_other_timesheet permissions can create timesheet records for other team members by submitting the QuickEntry form, even though they lack the create_other_timesheet permission. This bypasses authorization checks enforced in other parts of the application.

Impact Analysis

An attacker with valid credentials and specific permissions could manipulate timesheet records for other users, leading to inaccurate time tracking, financial discrepancies, or compliance violations. This could affect payroll, project billing, or audit trails.

Compliance Impact

This vulnerability could lead to unauthorized modifications of time records, potentially violating data integrity requirements under GDPR and HIPAA. Inaccurate records may result in non-compliance with audit and reporting obligations.

Mitigation Strategies

Upgrade Kimai to version 2.62.0 or later to address the authorization bypass in the QuickEntry controller. Ensure proper permission checks are enforced for timesheet creation.
