SQL Injection in Nur-Alam39 bus-ticket bus_info.php via busid parameter

Nur-Alam39 bus-ticket (no released versions; latest commit 459cabdbeb99c00225b26e46e3c2c30ae1de7bad) contains an unauthenticated SQL injection vulnerability in bus_info.php. The busid parameter received via HTTP POST is concatenated directly into a MySQL query (select * from bus_info where id=) without sanitization, escaping, or parameterization, and in a numeric (unquoted) context.
