Description

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via the "contact_name" and "contact_phone" HTTP POST parameters to "/wp-admin/admin-ajax.php" script. A remote unauthenticated  attacker can permanently store and execute arbitrary HTML and script code in user's browser in context of vulnerable website, when the website administrator visits a booking page.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
