Description

NamelessMC is website software for Minecraft servers. A Reflected Cross-Site Scripting (XSS) vulnerability was discovered in version 2.2.4 in the id parameter of the endpoint `/index.php?route=/queries/user/`. The application reflects user-supplied input from the id parameter into the HTML response without proper sanitization or output encoding. An attacker can craft a malicious URL containing JavaScript code. When a victim visits the crafted URL, the injected script executes in the victim's browser within the context of the vulnerable application. This could allow attackers to execute arbitrary JavaScript, potentially leading to session hijacking, phishing attacks, or manipulation of page content. Version 2.2.5 fixes the issue.
