Vulnerability Title
Kimai's User Preferences API allows standard users to modify restricted attributes: hourly_rate, internal_rate
Source: NVD (National Vulnerability Database)
Vulnerability Description
Kimai is an open-source time tracking application. In versions 2.52.0 and below, the User Preferences API endpoint (PATCH /api/users/{id}/preferences) applies submitted preference values without checking the isEnabled() flag on preference objects. Although the hourly_rate and internal_rate fields are correctly marked as disabled for users lacking the hourly-rate role permission, the API ignores this restriction and saves the values directly. Any authenticated user can modify their own billing rates through this endpoint, resulting in unauthorized financial tampering affecting invoices and timesheet calculations. This issue has been fixed in version 2.53.0.
