There is an XSS vulnerability in Booking In PHP, at line 111, we can see that the value is equal to the value of the variable $id, and the $id controllable variable is determined by user input and output directly. At this time, we can construct a closed XSS statement. The payload is "><script>alert (" ace ")</script>, and then we can construct a pop-up window

<input type="hidden" name="movie_id" value="<?php echo $id; ?>">
