|---|
| Description | patappointtime.php reads client-controlled day, time, and appdate at lines 46-50. It only checks that the submitted day name matches the calendar day at lines 53-57; it never compares either value with the selected doctor's day1/day2/day3 or timeslot1/timeslot2/timeslot3 values loaded at lines 19-30. The unchecked values are inserted into appointment at line 86. A doctor configured for Monday 09:00, Wednesday 10:00, and Friday 11:00 was successfully booked for Sunday 23:59. Patients can create appointments outside the physician's availability and disrupt clinic scheduling. |
