Caldera Forms <= 1.5.4 - Authenticated Cross-Site Scripting (XSS)

Description

Version 1.5.4 and earlier of Caldera Forms is vulnerable to a reflected cross-site scripting vulnerability in the "edit" parameter, which is not properly escaped before being printed in an HTML attribute. An attacker can use this to craft URLs that, when clicked, result in malicious JavaScript being executed. Because Caldera Forms uses 'wp_rest' nonces to access the WordPress REST API – a common practice among plugin developers – this Javascript may include anything the user is capable of doing in the REST API.
