Kimai is an open-source time tracking application. Prior to 2.58.0, PATCH /api/timesheets/{id}/restart, PATCH /api/timesheets/{id}/duplicate, and the web duplicate workflow can derive a new record from an owned historical timesheet after the user's access to its project or activity has been revoked. TimesheetVoter evaluates the own-timesheet permission before current team access, and its canStart() logic validates object visibility but does not verify the user's current team access to the referenced project and activity. An old entry therefore acts as a persistent capability to create new time records under an unauthorized project and activity, corrupting budgets, statistics, reports, and invoices after an administrative revocation. This issue is fixed in version 2.58.0.
