Cross Site Scripting vulnerability in JavaScript Library jquery-ui v.1.13.1 allows a remote attacker to obtain sensitive information and execute arbitrary code via a crafted payload to the window.addEventListener component. NOTE: this is disputed by the Supplier because it cannot be reproduced, and because the exploitation example does not indicate whether, or how, the example website is using jQuery UI.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
