itsourcecode University Management System add_result.php क्रॉस साइट स्क्रिप्टिंग

Successful exploitation of CVE-2026-4356 enables an attacker to execute arbitrary JavaScript code within the context of a user's browser session. This can lead to various malicious activities, including session hijacking, phishing attacks, and defacement of the application. An attacker could steal sensitive user data, such as login credentials or personal information, and use it to gain unauthorized access to the system. The remote nature of the vulnerability means it can be exploited from anywhere with network access to the affected system.

Organizations utilizing itsourcecode University Management System version 1.0, particularly those with publicly accessible instances, are at risk. Shared hosting environments where multiple users share the same server instance are also at increased risk, as a successful exploit could potentially impact other users on the same server.
