Summary

SourceCodester User Account Generator 1.0 contains a Cross-Site Scripting (XSS) vulnerability in the Username Prefix field. Due to improper sanitization of user-supplied input when rendering generated account data to the DOM, persistent injection of malicious HTML elements that execute when clicked by users is possible.

Risk Assessment

A remote attacker could execute arbitrary JavaScript in the user's browser session context, potentially leading to session hijacking or data theft. The persistent nature of the injection increases risk for all users viewing generated accounts.

Recommendation

Apply proper sanitization and encoding of input in the Username Prefix field and when rendering data to the DOM. Consider updating or retiring the vulnerable application.
