The ThemeHunk Customizer plugin for WordPress, versions up to and including 2.8.7, contains a reflected cross-site scripting (XSS) vulnerability due to improper neutralization of input during web page generation. This flaw (CWE-79) allows an attacker to inject malicious scripts that execute when a user interacts with crafted web content. The CVSS v3.1 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.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the victim's browser, potentially leading to theft of sensitive information, session hijacking, or other malicious actions within the context of the affected web application. The reflected nature means the attack requires user interaction, such as clicking a crafted link.

No official patch or remediation information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should consider disabling or restricting use of the ThemeHunk Customizer plugin or applying web application firewall (WAF) rules to detect and block reflected XSS attempts targeting this plugin.
