## Technical details

A Cross-Site Scripting (XSS) vulnerability exists in the WPMU DEV Forminator plugin for WordPress in versions up to and including 1.53.1. The flaw is caused by improper neutralization of user-supplied input during web page generation (CWE-79). An unauthenticated remote attacker can exploit this by tricking a user into performing an action, such as clicking a crafted link or visiting a specific page, to execute malicious JavaScript in the context of the victim's browser. This can lead to session hijacking or unauthorized actions performed on behalf of a privileged user. The issue is resolved in version 1.53.2.
