The vulnerability CVE-2025-67964 in favethemes Homey Core (<= 2.4.3) is a reflected cross-site scripting (XSS) issue caused by improper input neutralization during web page generation. This allows an attacker to craft malicious input that, when reflected by the application, executes arbitrary scripts in the victim's browser. The CVSS 3.1 base score is 7.1, indicating 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 can allow attackers to execute arbitrary scripts in users' browsers, potentially leading to theft of sensitive information, session hijacking, or other malicious actions affecting confidentiality, integrity, and availability of user data. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component.
