Description
Kimai before 2.62.0 fails to validate create_other_timesheet permission in the QuickEntry controller when creating new timesheets. Authenticated users with view_other_timesheet and edit_other_timesheet permissions can create timesheet records for team members by submitting the QuickEntry form, bypassing authorization checks enforced elsewhere.
