Online Booking & Scheduling Calendar for WordPress by vcita <= 4.5.1 - Authenticated (Subscriber+) Stored Cross-Site Scripting

The Online Booking & Scheduling Calendar for WordPress by vcita plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the vcita_save_user_data_callback() function in all versions up to, and including, 4.5.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject malicious web scripts and update settings.
