Advisory
Source description from Wordfence Intelligence, credited to yuyudhn.
The WP Time Slots Booking Form plugin for WordPress is vulnerable to authorization bypass due to improper capability checks throughout the ~/cp-admin-int-add-booking.inc.php file in versions up to, and including, 1.1.83. This makes it possible for authenticated attackers with editor-level privileges to modify some of the plugin's settings.
