## Technical details

The Ays Pro Popup box plugin for WordPress (versions <= 6.2.9) contains a reflected Cross-Site Scripting (XSS) vulnerability due to improper neutralization of user-supplied input during web page generation (CWE-79). An unauthenticated remote attacker can exploit this by crafting a malicious URL and tricking a user into visiting it. Successful exploitation allows the execution of arbitrary JavaScript in the context of the victim's browser session, potentially leading to session hijacking or unauthorized actions on behalf of a privileged user. The vulnerability is patched in version 6.3.0.
