Executive Summary

CVE-2026-32250 is a Reflected Cross-Site Scripting (XSS) vulnerability in NamelessMC website software for Minecraft servers, specifically in version 2.2.4 and earlier. The vulnerability exists in the id parameter of the /index.php?route=/queries/user/ endpoint, where user-supplied input is reflected into the HTML response without proper sanitization or output encoding.

An attacker can craft a malicious URL containing JavaScript code. When a victim visits this URL, the injected script executes in their browser within the context of the vulnerable application.

This flaw allows attackers to execute arbitrary JavaScript, which can lead to session hijacking, phishing attacks, or manipulation of page content.

Detection Guidance

This vulnerability can be detected by testing the vulnerable endpoint `/index.php?route=/queries/user/` with the `id` parameter to see if it reflects unsanitized input in the HTML response.

One way to detect it is by crafting a URL with a simple JavaScript payload in the `id` parameter and observing if the script executes or appears in the response.

• Use curl or wget to send a request with a test payload, for example: curl -i "http://yourserver/index.php?route=/queries/user/&id=<script>alert('XSS')</script>"
• Check the HTTP response for the presence of the injected script tag without proper encoding.
• Alternatively, use a web vulnerability scanner that supports reflected XSS detection against the affected endpoint.

Mitigation Strategies

The immediate step to mitigate this vulnerability is to upgrade NamelessMC to version 2.2.5 or later, where the issue is fixed.

Until the upgrade can be applied, consider implementing web application firewall (WAF) rules to block requests containing suspicious script tags in the `id` parameter.

Additionally, educate users to avoid clicking on suspicious or untrusted URLs that may exploit this vulnerability.
