Sourcecodester Student Grades Management System Using PHP and MySQL v1.0 – Stored Cross-Site Scripting (XSS)

Details:

Description:

Stored Cross-Site Scripting (XSS) is a vulnerability where malicious scripts are permanently stored on the target server (in databases, message forums, comment fields, etc.) and executed when other users retrieve the stored data. Unlike reflected XSS, the malicious payload persists and affects multiple victims without requiring them to click a malicious link. The attack occurs when user input is saved without proper sanitization and later rendered in other users’ browsers without adequate output encoding.
