CVE Publication: https://www.cve.org/CVERecord?id=CVE-2025-6477
Summary
A Stored Cross-Site Scripting (XSS) vulnerability was identified in the system endpoint of the Student Result Management System 1.0 (SRMS 1.0) application by Source Codester. This vulnerability allows attackers to inject malicious scripts into the School Name parameter. The injected scripts are stored on the server and executed automatically whenever the affected page is accessed by users, posing a significant security risk.

This lack of validation allows attackers to inject malicious scripts, which are then stored on the server. Whenever the affected page is accessed, the malicious payload is executed in the victim's browser, potentially compromising the user's data and system.
