Deeper analysis
CVE-2025-67964 is an improper neutralization of input during web page generation vulnerability, enabling reflected cross-site scripting (XSS) as classified under CWE-79. It affects the Homey Core WordPress plugin (homey-core) developed by favethemes, impacting all versions from n/a through 2.4.3 inclusive. The vulnerability was published on 2026-01-22 with a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L).
Attackers can exploit this vulnerability remotely over the network with low complexity and no required privileges, though it necessitates user interaction such as clicking a malicious link. By injecting crafted payloads into reflected inputs, adversaries can execute arbitrary JavaScript in the context of a victim's browser, potentially leading to session token theft, account takeover, or phishing within the site. The changed scope and low impacts on confidentiality, integrity, and availability still render it a high-severity issue for sites using affected plugin versions.
Mitigation details are available in the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/homey-core/vulnerability/wordpress-homey-core-plugin-2-4-3-cross-site-scripting-xss-vulnerability?_s_id=cve, which documents the vulnerability specific to Homey Core plugin version 2.4.3.
