The WP Booking System plugin for WordPress has a security issue that allows unauthorized changes to be made to data. This is because the wpbs_refresh_calendar_editor function in versions up to 2.0.19.10 does not have a check for user capabilities. This means that anyone who is logged in and has subscriber-level access or higher can make changes to calendars without permission.
