Technical details

A Cross-Site Scripting (XSS) vulnerability exists in the JetEngine plugin for WordPress (versions <= 3.8.10) due to improper neutralization of user-supplied input during web page generation (CWE-79). The flaw is unauthenticated, meaning an attacker does not need a login to initiate the attack, though successful exploitation requires user interaction (typically a victim clicking a malicious link). By leveraging this vulnerability, an attacker can execute arbitrary JavaScript in the context of the victim's browser session, which can lead to session hijacking or unauthorized administrative actions. The issue is resolved in version 3.8.10.1.
