Description
The Booking calendar, Appointment Booking System WordPress plugin through 3.2.36 does not properly sanitize uploaded SVG files, allowing unauthenticated attackers to upload a file that bypasses the Booking calendar, Appointment Booking System WordPress plugin through 3.2.36's script-stripping and executes arbitrary JavaScript when the SVG is opened, including in the session of an administrator who reviews the submitted booking.
