Name of the Vulnerable Software and Affected Versions The Appointment Booking Calendar — Simply Schedule Appointments Booking Plugin WordPress plugin versions prior to 1.6.7.55

Description The issue is related to the lack of sanitization and escaping of some Appointment Type settings in the plugin, which could allow high-privilege users, such as admins, to perform Cross-Site Scripting attacks, even when unfiltered html is disallowed.
