## Technical details

This vulnerability is a reflected cross-site scripting (XSS) flaw in JetEngine (versions through 3.8.14.2) caused by improper neutralization of user input during web page generation. The vulnerability is accessible to unauthenticated attackers but requires user interaction—a victim must click a malicious link or visit a crafted page for the attack to succeed.
