Technical details
This is a Reflected Cross-Site Scripting (XSS) vulnerability in the Unlimited Elements For Elementor plugin affecting versions up to 2.0.16. The vulnerable code fails to sanitize the 'data[name]' parameter before outputting it in responses from the show_preview AJAX action. The attack vector is network-based and requires no authentication; however, the attacker must trick a user into visiting a malicious link. The nonce protection on the AJAX endpoint can be bypassed because the nonce is publicly retrievable from any page that loads the plugin. A successful exploit allows an attacker to execute arbitrary JavaScript in the victim's browser context, potentially stealing session cookies, credentials, or performing actions on behalf of the user.
