提出 #79844: Reflected Cross-Site Scripting (XSS) Vulnerability in the Name Parameter of Canteen Management System 1.0 by SourceCodester

# Description
A Reflected Cross-Site scripting (XSS) vulnerability has been discovered in the Canteen Management System 1.0 by SourceCodeSter. The vulnerability affects the 'Add Customer' form in the 'createcustomer.php' source code and allows an attacker to inject malicious code into the 'name' parameter. The injected code is then reflected back to the user's browser and executed, allowing an attacker to steal sensitive information, perform actions on behalf of the user, or redirect the user to a malicious site. This vulnerability can be remotely exploited and has the potential for code execution. It's important to note that this vulnerability is only exploitable if the user clicks on a link or submits a form containing the malicious code.
