The GoodLayers Modernize theme versions up to 3.4.0 contain a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This flaw allows attackers with low privileges and requiring user interaction to inject malicious scripts that can affect confidentiality, integrity, and availability to a limited extent. The CVSS vector indicates network attack vector, low attack complexity, low privileges required, user interaction needed, and scope changed.

Successful exploitation can lead to limited confidentiality, integrity, and availability impacts via stored XSS attacks. This may allow attackers to execute arbitrary scripts in the context of affected users, potentially leading to session hijacking, defacement, or other malicious actions within the scope of the vulnerable application.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider restricting input sources and applying web application firewall (WAF) rules to detect and block XSS payloads. Monitor vendor channels for updates and apply patches promptly once released.
