## Technical details

A Cross-Site Scripting (XSS) vulnerability exists in the JetEngine plugin for WordPress due to improper neutralization of input during web page generation (CWE-79). The vulnerability is exploitable by unauthenticated remote attackers and requires user interaction (typically from a privileged user) to execute. Successful exploitation allows an attacker to inject arbitrary HTML or JavaScript payloads into the context of the victim's browser session. This can lead to session hijacking, unauthorized administrative actions, or site defacement. The issue is resolved in version 3.8.10.
