WP Simple Booking Calendar <= 2.0.10 - Reflected Cross-Site Scripting
Vulnerability Description
The WP Simple Booking Calendar plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg & remove_query_arg without appropriate escaping on the URL in all versions up to, and including, 2.0.10.
