CVE-2026-24973 describes a reflected cross-site scripting vulnerability in the NooTheme CitiLights product up to version 3.7.1. The vulnerability is caused by improper neutralization of user input during web page generation, enabling attackers to inject and execute arbitrary scripts in users' browsers. The CVSS 3.1 base score is 7.1, indicating a high severity with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability at low levels.

Successful exploitation of this vulnerability could allow attackers to execute arbitrary scripts in the context of the affected web application, potentially leading to theft of sensitive information, session hijacking, or other malicious actions impacting confidentiality, integrity, and availability to a limited extent. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official patch or workaround information is provided in the available data. Until a fix is available, users should exercise caution with untrusted input and consider implementing web application firewall (WAF) rules to detect and block reflected XSS attempts.
