CVE-2026-32250: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in NamelessMC Nameless
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.
AI Analysis
Technical Summary
NamelessMC 2.2.4 is vulnerable to reflected Cross-Site Scripting (CWE-79) due to improper neutralization of user input in the id parameter of the /index.php?route=/queries/user/ endpoint. The application reflects this parameter directly into the HTML response without proper sanitization or encoding, enabling attackers to execute arbitrary JavaScript in the context of the affected site. This vulnerability is resolved in version 2.2.5.
Potential Impact
Successful exploitation allows attackers to execute arbitrary JavaScript in the victim's browser, which can lead to session hijacking, phishing, or manipulation of web page content. The CVSS score of 4.3 reflects a medium impact primarily on confidentiality with no direct impact on integrity or availability.
Mitigation Recommendations
Upgrade NamelessMC to version 2.2.5 or later, where this vulnerability has been fixed. Since the vendor has released a fixed version, applying this official update is the recommended remediation. No other mitigation guidance is provided or necessary.
